Question 1117037
Graph at least two full periods of the following function. Label the 5 key points on one period. Give the amplitude and period of the function.. y=-2sin(2x) 
there is an 
x y empty chart for 5 points. (I assume 0, pi/2, pi, 3pi/2, and 2pi)
----
{{{graph(400,400,-0.5,6.5,-4,4,-2sin(2x))}}}
f(x) = -2sin(2x)
f(0) = -2*sin(0) = 0
f(pi/2) = -2sin(2(pi/2)) = -2sin(pi) = 0
f(pi) = -2sin(2*pi) = 0
f(3pi/2) = -2sin(2(3pi/2) = -2sin(3pi) = 0
f(2pi) = -2sin(4pi) = 0
----
amplitude = |-2| = 2
period = (2pi)/2 = pi radians
Cheers,
Stan H.
