1. What is the amplitude, period, and frequency of this function graphed?

2. What is the equation of the midline of the function

3. Write a cosine function that represents the graph

the period is 3.14 (the distance from one peak to the next)

the amplitude would be 2 as it is the distance between the centre point and peak

the frequency is 1/3.14

the equation of the midline of the function would be x=-3

ignore if blatantly wrong  haha

You are close...HMB....!!!

The equation of the midline is  y = - 3

3.  The equation is

y = 2cos (2x) - 3
