How do you sketch y = 3 sin (2x-2)?

When written in a different form, y = 3*sin(2(x-1))+0, I would say that the amplitude is 3, the period is pi, and the phase shift is 1.

Explanation:

Notice that the sine wave completes one full cycle between (1,0) and (4.14, 0). That is a period of pi.

The amplitude is 3 units.

The phase shift is right 1 unit, as you can see from (1,0) being a "starting" point for a sine wave.
