Question

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

Answer 1

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

Answer 4

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

Answer 5

: f(x) = -  4 cos(3x – π)  +  1   ...   in this form the characteristics are:

amplitude = 4

period = 2π ⁄ 3

phase shift = -π radians

vertical shift = +1

average = +1   =   midline

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

HOWEVER, because of the -π phase shift, this equation is equivalent to:

y = 4 cos(3x)  +  1   ...   and in this form the characteristics are:

amplitude = 4

period = 2π ⁄ 3

phase shift = 0

vertical shift = +1

average = +1   =   midline
