Question

Find the equation of the cosine graphed.

Answer 1

C) y = -cos(x) +2

Explanation:

The centerline is 2, so 2 is added. That leaves out choices A and B.

There is a minimum (not a maximum) at x=0, so the multiplier is negative, eliminating choice D.

The correct equation is that of C: y = -cos(x) +2.
