Hey there! :)
Answer:
[tex]y= cos (x+ \pi })[/tex]
Step-by-step 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:
[tex]y= cos (x+ \pi })[/tex]
