Question

Which is the graph of y= cos(x-pi)

Answer 1

graph attached

Explanation:

A graph is a pictorial representation that represent the relationship between two or more things.

Cosine function is periodic with period
`2\pi` . If the point
`(x,y)` lies on the graph, point
`(x+2k\pi ,y)` will also lie on the graph where k is any integer.

Here,

`cos(x-\pi )=cos[-(\pi -x)]=cos(\pi -x)=-cos x`
