Question

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

Answer 1

Answer:

graph attached

Step-by-step 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,

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