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 $y=-2\sin (2\pi x+4\pi )$ has amplitude $|-2|=2$, period $\frac{2\pi }{2\pi }=1 $, and phase shift $\frac{- 4 \pi }{2\pi }=-2$.
