Answer
The Amplitude is $|-2| = 2$
The Period is $\frac{2\pi}{|1|} = 2\pi$
The Horizontal shift is $\frac {\pi}{6}$ units to the right
See graph below.
Work Step by Step
For $y=a\sin c(x−h) + k$ $y =a \cos c(x−h) + k$,
Amplitude: $|a|$, Period: $\frac{2\pi} {|c|}$,
Horizontal Shift: h
The question asks for a graph, amplitude, period, and horizontal shift of the function.
Given $y = -2 \sin (x - \frac{\pi}{6})$
The Amplitude is $|-2| = 2$
The Period is $\frac{2\pi}{|1|} = 2\pi$
The Horizontal shift is $\frac {\pi}{6}$ units to the right
See graph below.
