The given function .

The above equation is equal to this statement .

Find the amplitude.

                             (The coefficient of is 1)

Next, find the period.

         (Substitute )

                                    (Simplify)

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

, so the phase shift is , the parent graph is shifted to the left.

Use the amplitude and period to graph the function.

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