Question

What are the amplitude, period, and midline of the function?

Amplitude: 4; period: 2π; midline: y = −1

Amplitude: 8; period: 2π; midline: y = 1

Amplitude: 8; period: π; midline: y = −1

Amplitude: 4; period: π; midline: y = 1

Answer 1

1

Answer 2

amplitude is measured from the midline, which is the equation of the line hving equal amplitudes above and below it. any sine curve has freq 2pi

Answer 3

Amplitude: 4; period: 2π; midline: y = −1
