When written in a different form, y=3⋅sin(2(x−1))+0, I would say that the amplitude is 3, the period is π, 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 π.

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.
