Graph each sinusoidal function over two complete cycles
a)f(x) = 2 cos x - 3
Sketch a cosine curve.
Amplitude is 2 so label the y-intercept (0,2)
The lowest point is (pi,-2)
Move each point of the curve down 3.
--------------------------------------------
b)f(x) = 4 sin x - 2
Sketch a sine curve.
Amp is 4
Move each point of the curve down 2.
----------------------------------------
c)f(x) = 1/2 cos x +3
Sketch a cosine curve.
Amp is 1/2
Move each point up 3.
