Question

I can send the options, I get how to do this, I’m just not really getting this problem though, can you give a quick break down?

Answer 1

The function in the image corresponds to a cosine function. Notice that the maximum is around y=5 and the minimum is at y=2. Therefore, the midline is:

$y=\frac{5+2}{2}=3.5$

The answer is y=3.5 approximately
