Tuesday HW/Review for TEST!

Remember to bring in STAMPs (due Wednesday!) 

• Count them, Record total on front
• Staple together, put in an envelope, create some sort of organized system to turn them in!
• DOUBLE CHECK YOUR TOTAL! (if it's wrong you'll get a 0)

#5 & 6 are below: Directions: Determine the equation to the following graph. (DO NOT CONSIDER PHASE SHIFT FOR THESE PROBLEMS! THESE GRAPHS DO NOT INCLUDE PHASE SHIFT!)
5)

 6)

*Along with the HW if you are still feeling shaky on any of the subjects below do some studying, some more extra practice!*

Here are the topics covered:

• Parent functions (sin, cos)
• amplitude (|a|) and how it affects the parent function
• Vertical shift and how it affects the parent function
• Determining Period (=2π/b) 
• (the only new thing to pay attention to when writing equations from graphs)
• plug in period (into the equation above) and solve for b
• Phase shift and how it affects the parent graphs (shift the starting point (x=0) for any given function)
• Determining equations based on a graph (consider midline, amplitude, period, shape, and +/-)
• Don't worry we WILL NOT be using phase shift to determine equations only those 5!!
