Which transformations are needed to change the parent cosine function to
y = 0.35cos(8(x-pi/4))

C:  vertical compression of 0.35, horizontal compression to a period of pi/4, phase shift of pi/4 units to the right

Step-by-step explanation:

Here's a list of the changes and their effect:

So, the function is shifted units to the right, then it is compressed by a factor 8 horizontally, and a factor 0.35 vertically.

i can you with this question sweetie!
