Question

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

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

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

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

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