Question

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

Answer 1

the answer is C i got it right on ED

Explanation:

Answer 2

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,

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
`\pi/4`
