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

a. Amplitude: 3; period: pi over 2; phase shift: x = pi over 4; midline: y = 2
b. Amplitude: −3; period: pi over 2; phase shift: x = pi over 2; midline: y = 2
c. Amplitude: 2; period: pi over 4; phase shift: x = pi over 4; midline: y = −3
d. Amplitude: 2; period: pi over 4; phase shift: x = pi over 2; midline: y = −3

What have you done so far, Silver?
Compare your f(x) to y = a sin (bx + c) + d.
By doing so, you should be able to determine the values of a, b, c and d by inspection.
