You can put this solution on YOUR website! Use the equation y= -4 cos 1/3(x+pi/2) + 1 to identify the following characteristics of it's graph:
basic curve Acos(Bx-C), A=amplitude, period=2π/B, phase shift=C/B
For given equation: A=4, B=1/3, C=π/6
Period: 6π
Vertical shift: 1 unit up
Maximum value of the graph=5
Amplitude=4
Horizontal shift:π/2 (to the left)
Equation of the midline: y=1
Minimum value of the graph=-3
