TEST TOMORROW!

STUDY, STUDY, STUDY! Your only homework it to prepare to ace tomorrow's test and end the first quarter on a high note!

Here's a breakdown of some of the questions on tomorrow's test...primarily sections 1.5 to 1.7, some 1.4

  • Find (f + g), (f - g), (fg), and/or (f/g) (Combinations of Functions)
  • Evaluate (ex: (f + g)(2))
  • Compositions of functions
  • Use compositions to determine if two functions are inverses
  • Find the inverse of a function (switch x, y and solve for y)
  • Graph f(x), f inverse, and y=x
  • Determine if a function is one-to-one (horizontal line test)
  • Shifting of functions
  • Linear Regression (Line of Best Fit)
    • Find the equation and correlation (r)
    • Interpret correlation (strength and direction)
    • Solve for y given a value of x
    • Solve for x given a value of y
Good luck! I hope you all get an A+!
