What are the amplitude, period, phase shift, and midline of f(x) = −4 cos(3x − π) + 1?

Amplitude: 4; period: 2 pi over 3; phase shift: x = pi over 3; midline: y = 1

Step-by-step explanation:

Use the form a cos (bx-c)+d to find the amplitude, period, phase shift, and vertical shift.

a=-4

b=3

c=pi

d=1
