The given function .

\ \

The above equation is equal to this statement .

Find the amplitude.

                                  (The coefficient of is 2)

Next, find the period.

                 (Substitute )

, so the vertical shift is 3.

, so the phase shift is to left.

The vertical shift is 3 and graph midline .

The amplitude is 2 and draw the dashed lines 2 units above and below the midline at 

.

The period is , the graph will be stretched.

The graph shift to the left.

Use the amplitude and period to graph the function.
