Please see below.
Work Step by Step
Please note that a sine function $y=A\sin (Bx-C)$ has amplitude $|A|$, period $\frac{2\pi }{B}$, and phase shift $\frac{C}{B}$.
So the function $y=3\sin (2\pi x+4)$ has amplitude $|3|=3$, period $\frac{2\pi }{2\pi }=1 $, and phase shift $\frac{- 4}{2\pi }=-\frac{2 }{\pi }$.
