There is a phase shift to the left.

Question 7

Which is the graph of

Revolt · Accepted Answer

On a coordinate plane, a curve crosses the y-axis at y = 1 and then decreases. It then increases and decreases again.

Question 8

Which did you include in your solution?

Revolt · Accepted Answer

The period of the function is [image 1] ,so every [image 2] ,the cycle will be again.; If the h-values differ by multiples of ,the function will have the same graph.
