# How do you graph and list the amplitude, period, phase shift for y=4cos2x?

Amplitude $A = 4$
Period $T = \pi$
Phase shift $C = 0$

#### Explanation:

Amplitude $A = 4$

Period $T = \frac{2 \pi}{2} = \pi$

Phase shift $C = 0$

The graph of $y = 4 \cdot \cos 2 x$

God bless...I hope the explanation is useful.
