Question

What is the amplitude, period, phase shift and vertical displacement of `y=3sin(3x-9)-1`?

Answer 1

Amplitude = 3
Period = 120 degrees
Vertical Displacement = -1

Explanation:

For period use the equation: T = 360/n

n would be 120 in this case because if you simplify the equation above it would be:

`y = 3sin3(x-3) -1`

and with this you use the horizontal compression which would be the number after "`sin`"
