II's Day

Let's keep up the great work!

Tomorrow it's back to quadratics and parabolas and vertices and x-intercepts and such.

Tonight, please complete the following in your textbook:

Page 95: 1-8, 43, 45

Here is tomorrow night's homework (in case you'd like to get ahead):

Page 95: 13-25 (odd)


See you all tomorrow!

Monday......

I know this morning definitely felt like a Monday to me....I'll try to bring some higher energy to the math classroom tomorrow. You too! :)

Tonight, please complete the following in your textbook:

Page A61: 83, 85, 87, 89, 95, 97, 109, 111 (all in Appendix B.3)

This will give us some practice with the different ways to solve quadratics--factoring, quadratic formula, and solving with square roots.

Use your notes from today to help! See you all tomorrow!

Enjoy Your Weekend!

Hopefully you aced today's test!

On Monday we're moving on to new stuff! We'll start with a review of everything we know about quadratics (section 2.1) and factoring on Monday!

Until then, enjoy the beautiful weather, go outside, rest up, and be ready to work hard!

See you all on Monday!

Test Again Tomorrow! (Round 2)

Tomorrow's test is all "no graphing calculator." Like today's test, it covers anything from section 1.1 through 1.6 in our textbook/notes.

To be honest, tomorrow's test is more difficult than today's was....so STUDY, STUDY, STUDY!

Here's an outline of tomorrow's test (all open-ended, no graphing calculator):

**If you have a scientific or other non-graphing calculator, feel free to bring it to use. Otherwise I will give you a basic 4-function calculator to use.*

• Write an equation of a line perpendicular to a given line and through a given point (like #1 on the multiple choice) (1.1)
• Construct a mapping of points and determine if it is a function (1.2)
• Evaluate a piecewise function (1.2)
• Determine where a function is increasing, decreasing, constant, positive, negative (1.3, or "Analyze the Graph" type questions)
• Identify three parent functions given their shape (1.4)
• Describe any transformations (shifts) in a function given an equation (1.4)
• Write an equation of a function given a description of transformations (shifts) and reflections (1.4)
• Graph four equations based on shifts and reflections (1.4)
• Add, subtract, multiply, divide functions (1.5)
• Evaluate combinations of functions (1.5)
• Find/evaluate compositions of functions (1.5)
• Find the inverse of functions (1.6)
• Find the inverse given 4 coordinate pairs (1.6)
• Use composition to determine if functions are inverses (1.6)
• Graph a linear equation, its inverse, and the identity function (1.6)

Study! Good luck! Feel free to email with any questions!

STUDDDDDDYYYYYYYYY

Tomorrow starts a HUGE two day span....two days of PreCalc tests! Woooo!

This is all based on unit 1, sections 1.1 to 1.6.

Tomorrow's test is "graphing calculator allowed." Here's a breakdown of the test (tomorrow):

• 9 Multiple choice
• Study the pre-test I gave you today! Tomorrow's questions are the same types with different numbers!
• Here are the answers to the pre-test in case you're studying at home (and want to make sure you're correct):
• 1.) A
• 2.) B
• 3.) D
• 4.) D
• 5.) B
• 6.) C
• 7.) A
• 8.) B (SKIP; THIS IS NOT ON THE TEST)
• 9.) D
• 10.) C
• Open-Ended
• Determine if lines are parallel, perpendicular, or neither, given points
• Find the slope for each line
• Same slope = parallel, "opposite reciprocal" slopes = perpendicular, otherwise they're "neither"
• Use the calculator to find any relative maxima/minima
• State the domain and range given a graph (no need for the calculator)
• Find x-intercepts of a function (zeros) using the graphing calculator
• Extra Credit:
• Factor to simplify an expression
• Add/subtract/multiply/divide fractions (and know order of operations)

Use your old quizzes to study! They'll have examples of all of these types of questions (except for the extra credit).

I'm looking forward to lots of A's! Study and be ready!

Oh, so this is the blog?!

Hello first time blog-checkers! Check this every day! (you have time, it only takes about 1 minute, max....just check this in between all of your social networking :) )

Tonight's Homework:
Page 69: 9a, 11a, 13a, 15, 17, 19; 53, 55, 57, 59,61  (for 53,55,57,59,61 just find the inverse)

Enjoy! Tomorrow we'll finish section 1.6! Then we'll answer some questions, and on Thursday it's test time!

Thursday's Test:

• Graphing calculator allowed
• 9 multiple choice (study your pre-test!)
• A few open-ended (that require the calculator, like relative min/max questions)

Friday's Test:

• No graphing calculator
• All open-ended
• Show all work!

No homework tonight....kinda

How did you do on the quiz? I'll be here on Wednesday after school if you'd like to go anything....this is a big week, with tests on Thursday and Friday!

Tonight, no official homework. However, feel free to get a head start on the assignment below, which is tomorrow's homework: (**This is modified from what you saw in class**)

Page 69: —9a, 11a, 13a, —15, 17, 19, 53-61 (odd; just find the inverse)


Enjoy! See you all tomorrow for some more math!!!! :)

Weekend Homework! Yay!

Did you get an A on the quiz today? I'm looking forward to some great grades!

This weekend, please complete the graphing assignment I passed out in class. Your job is to use the two graphs (of f and g) to create a new graph of (f+g)!

If you're having trouble, I recommend creating a table like this (this is based on exercise 3 of the hw)....

 

I can read the graphs of f(x) and g(x) to find their values for a given y-coordinate. Then, I can add these to find (f+g)(x). Finally, I now have x-values and h(x) values to plot on a new graph! For instance, this table above tells me to plot (-2, 6) and (0,2) for my first two points on h(x). After I plot all four points, I simply need to "connect the dots" with straight lines!

Enjoy your weekend! On Monday we'll start section 1.6 (inverses!)--the last section of this unit! Next week we will have our unit test over two days, Thursday and Friday! It's a big week!

And here's the homework in case you lost it!

Big Quiz Tomorrow!

Tomorrow's a big day....quiz time! Our quiz covers sections 1.3, 1.4, and 1.5, which includes the "analyze the graph" type questions!

Don't forget--you also have an extra credit homework opportunity (the worksheet passed out in class) if you'd like! You have to turn it in tomorrow though! If you want to really maximize this chance to study, I would recommend graphing the equations (in addition to describing the transformations).

Here's a breakdown of your quiz...which is by far our most heavily weighted quiz thus far, so study, come by if you need help (after school or tomorrow before class), and get an A! The section number is provided in parentheses.

• Sketch the shape of 3 parent functions (know them all!) (1.4, back cover of textbook)
• Graph 4 functions based on shifts and reflections (1.4)
• Find the domain of a radical (square root) function (1.3)
• Find the domain of a rational (a fraction) function (1.3)
• Find the relative min/max of a function using the graphing calculator (1.3)
• Adding/Subtracting/Multiplying/Dividing Functions (1.5)
• Compositions of Functions (1.5)
• Evaluating compositions and combinations of functions (1.5)
• Write the equation of a function given its shifted/reflected graph (1.4)
• "Analyze the Graph" questions (1.2, 1.3, study last night's homework)
• Evaluate f(#)
• Evaluate f(x) = #
• Find zeros (x-intercepts)
• Find y-intercepts
• Intervals of Increasing/Decreasing/Constant
• Intervals where a function is positive/negative
• Domain
• Range
• NOTATION!

Get an A! This is a big quiz, and next week will be a big week...on Monday/Tuesday we'll finish section 1.6, and then it's time for a unit test!

Wednesday HW!

Tonight, please complete the "Analyze the Graph" practice worksheet (on the back of the table we made in class). Tomorrow I'll provide you with an answer key so that you can use this to study!

Tomorrow, report directly to room 121 for the STAR test! You will be given a classwork grade based solely on your effort....try your best, get an A for the day!

If you lost your worksheet, tonight's homework is to find each of the following for the graph below:

• Domain
• Range
• Intervals where the function is...
• Increasing
• Decreasing
• Constant
• Positive; f(x) > 0
• Negative; f(x) < 0
• Relative Maximum (coordinates)
• Relative Minimum (coordinates)
• Absolute Maximum Value
• Absolute Minimum Value
• X-Intercept(s)
• Y-Intercept(s)

Toosday Homework

Tonight, please complete the combinations/compositions of functions worksheet that we started in class. If you can do this you know everything you need to know about section 1.5!

A few other reminders...

• STAR test in room 101 on Thursday!
• Quiz on sections 1.3 - 1.5 this Friday!
• Unit 1 test next week! (either Weds/Thurs or Thurs/Fri)
• Another "Analyze the Graph" pop quiz is looming....it'll happen sometime before our unit test...

See you all tomorrow for some review/quiz prep! Enjoy your afternoon!

Monday HW

Did some people really get 0's on a take home quiz? If you didn't turn in your multiple choice today, tomorrow is your last chance. I can't give you full credit, but any points will be better than a 0 on a quiz!

Tonight's (Monday) Homework: Some practice with arithmetic combinations and compositions of functions. You know I'm checking it!

Page 58: 7,9,13,15,17,19,35,37

See you all tomorrow! Enjoy!

Take Home Quiz!

We made it to the weekend after our first 5 day week!

This weekend, please complete the 12 multiple choice questions provided in class. This will be graded as a take home quiz! Use the links to the right if you don't have a calculator!

In addition, if you did not finish the "shifting, reflecting" (graphing and writing equations) worksheet that we started in class, please finish it and bring it back Monday. This will also be collected and graded!

So that means you have 2 things that will definitely impact your grade (more than a usual homework)...so do a great job! As always, email with any questions!

And enjoy the weekend!

Thursday HW

I know we're moving quick....I'm always after school on Mondays, Wednesdays, and Thursdays....you can also take advantage of the tutors here at the high school if you need help!

Tonight, please sketch the shape of each parent function on the worksheet provided. If you don't know the shapes, you can find them in the back of your book--there's a thicker page with some, and some are on the back cover (I think). It's super important that you do this for tomorrow's classwork assignment! If you don't have your homework, the classwork will be pretty tough!

See you all tomorrow.....and it's Friday!

Hump Dayyyyy!

We made it through our first real "hump day," as this is our first full week! Of course that calls for us to view this classic...


Tonight, please complete the following:

Page 39:17-20, 23, 25, 29, 31, 33, 105

The homework requires a graphing calculator. If you don't have one, I expect you to do one of the following to get it done:

• Come to my class after school, during school, or before school (I'm here around 6:50) to borrow one of mine!
• Borrow a friend's!
• Try to find an app for your phone that allows you to download one!
• http://wabbit.codeplex.com/
• Search for a graphing calculator online! (it might not have the same buttons as ours though)
• My google searches for "Graphing Calculator" quickly returned these...
• https://www.desmos.com/calculator
• http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
• If you google "TI84 Emulator" you can probably also download a calculator that looks like ours to your computer...
