Question

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

Answer 1

The general equation is:
y = A sin(Bx + C) + D
where
|A| is the amplitude
The period T =
`\large (2 \pi )/(B)`
The phase shift =
`\large (C)/(B)`
The 'y' shift = D
Now you need to plug in the value from the question.
