Sketch the graph of each function
jenyasd209 [6]

Answer:

See diagram

Step-by-step explanation:

First, consider the graph of the parent function y=\cos x. This function has the period 2\pi.

Rewrite the function y=2(1+\cos (x-\frac{\pi}{2})) as y=2+2\cos (x-\frac{\pi}{2}). The graph of this function has the same period of 2\pi, is twice streched and translated \frac{\pi}{2} units to the right and 2 units up graph of the parent function (see diagram).
