A is the amplitude
B helps determine the period
C is the horizontal shift
D is the vertical shift
1. y=-2sin(2x) 2. y=-pi cos((pi/2)x+pi)
I've been working on these problems for days so I would really appreciate if someone helped.
I found the period and amplitude and I think I found the horizontal shifts but I don't understand how to use the period to find the horizontal shift and I'm completely lost on how to find the vertical shift,please help
