The given function .

Compare the equation with phase shift function  and find a, b and h.

Here a = 1,  b = 1 and .

Since a = 1 and b = 1 amplitude and period of the function are same.

Since the phase shift .

As h < 0, the parent graph 

Use the amplitude and period to graph the function.

The amplitude is 1,  period is 1 and the graph shifted to the left.
