The graph of a periodic function is given below. a. What is the period of this function? b. What is the minimum value of this function? c. What is the maximum value of this function? d. What is the midline of this function? y = e. What is the amplitude of this function?

Solution

a. Period=4pi-pi=3pi

Minimum value means minimum value of y which is -3 .

c. maximum value means maximum value of y which is 0

d. midline is at the average of maximum and minimum

y=(0-3)/2=-1.5

amplitude = (0--3)/2 1.5
