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 "
