# How do you graph y=4cosx+4?

Jun 24, 2018

As below.

#### Explanation:

$y = 4 \cos x + 4$

Standard form of cosine function is $y = A \cos \left(B x - C\right) + D$

$A = 4 , B = 1 , C = 0 , D = 4$

$\text{Amplitude } = | A | = 4$

"Period ' = (2pi) / |B| = 2pi

"Phase Shift = -C / B = 0

$\text{Vertical Shift } = D = 4$
