The coordinates of the five quarter points for are given below. Use these quarter points to determine the y-coordinates of the quarter points of y=-2sin(-2x).
(0,0)
(π/2,1)
(π,0)
(3π/2,-1)
(2π,0)
(Type ordered pairs. Type exact answers, using π as needed)
the given points are for y=sinx
so dilate as required.
