C. The phase shift is ____. D. Sketch 2 full periods of the graph._____. For f(x) = 1-cos(pi x + pi/4): A. The amplitude is ____. B. The period is ___. C. The phase shift is _____. D. sketch 2 full periods of the graph.

Explanation / Answer

1 . f(x) = 3sin(pi x/4)

This is of the form y= A sin(Bx-C)

where amplitude A=3

period=2pi/B = 2pi/pi/4 =8

phase shift =C/B=0
