Question

What is the equation of the graph below?

Answer 1

Hey there! :)

Answer:

`y= cos (x+ \pi })`

Explanation:

Normally, in the parent function y = cos x, when X = π, Y = -1. However, in this graph, when X = 0π, Y = -1.

Therefore, there has been a horizontal shift of π to the left. The new equation would be:

`y= cos (x+ \pi })`
