What are the amplitude, period, phase shift, and midline of f(x) = −3 sin(4x − π) + 2? (6 points)

algol [13]

The parent function of $y=-3sin(4x- \pi )+2$ is $y=sin(x)$

The diagrams below show step by step transformation

As we can see from the graph $y=-3sin(4x- \pi )+2$ , the amplitude of the function is 3, period of $\frac{ \pi }{2}$ , phase shift of π and midline y=2
