# How do you graph  y=-2+cosx?

Sep 22, 2017

By providing numbers to x, you can find value of the function and graph it.

#### Explanation:

If x is 0, your function will be $y = - 2 + 1 = - 1$

If x is $\frac{\pi}{4}$ your function will be $y = - 2 + 0.707 = - 1.293$

etc. Now you can graph

graph{-2+(cosx) [-10.08, 9.92, -7.24, 2.76]}
