Problem 2 :

Problem 3 :

Problem 4 :

Identify the amplitude and period of the graph of the function.

Problem 5 :

Problem 6 :

Problem 7 :

Problem 8 :

Answer Key

1) Amplitude = 0.5 and period is 2.

2) Amplitude = 1.5 and period is π/2.

3) not a periodic function.

4) It has a pattern, but y-values is not repeating for each cycle. So, it is not a periodic function.

5) period = 3π, amplitude = 1

6) period = 1, amplitude = 0.5

7) period = π, amplitude = 4

8) period = 8π, amplitude = 3
