What is the amplitude, period, and phase shift of f(x) = −3 cos(4x + π) + 6?

Amplitude = 3; period = pi over two; phase shift: x = negative pi over four
Amplitude = −3; period = pi over two; phase shift: x = pi over four
Amplitude = −3; period = negative pi over two; phase shift: x = negative pi over four
Amplitude = 3; period = 2π; phase shift: x = negative pi over four

Answer:

amplitude =

[tex]3[/tex]

period =

[tex] \frac{\pi}{2 } [/tex]

phase shift =

[tex] - \frac{\pi}{4} [/tex]
