Trig graphs help

I have three questions in my book about the composite argument property that I'm not entirely sure about

"On your paper, draw an appropriate sketch and use it to write

as a cosine with a phase displacement."

My response:

y=5cos(x)-0.64350169

"Draw an appropriate sketch on your paper and use it to write

as a cosine with a phase displacement."

My response:

y=-3.1622777cosθ-3.4633437

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
