Answer:
Amplitude = 4; period = π; phase shift: x = negative pi over two
Step-by-step explanation:
In this problem you have to use the form a sin (bx-c)+d to find the amplitude, period, and phase shift.
Amplitude:4
Period : π
Phase shift: [tex]-\frac{\pi }{2}[/tex]
I hope this helped! Have an amazing day :)
