Question

I'm not sure if you multiply the 4 and 3 to find the Amp and I'm not sure what to do with the provided degrees.

Answer 1

Explanation:

This can be re-written as

7 + 4 cos (3Φ - 30)

amplitude is 4

period = 2 pi / 3 ( or 120 degrees)

Phase is 30 degrees

translation is to the right and UP 7
