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

The parent cosine function was  horizontally shrinked by a factor of 8 , vertically streched by a factor of 0.35  and shifted to the right by pi/4 units,

Step-by-step explanation:

Given : The parent cosine function y=0.35 cos (8(x-π/4))

The transformation of cosine function are shown through graph attached

we can see in the graph there is vertically stretch downward of 0.35

and there is horizontally shrink  with factor  8

and also the cosine function is shifted towards right with

the answer is 62.8 cubic units
