Question
For f(x) = 3sin (pi x/4) = -3sin(pi x/4): A. The amplitude is ____. B. The period is ______. C The phase shift is ____ D. Sketch 2 full periods of the graph. For = 2 + sin(2x + pi/2): A. The amplitude is ____. B. The period is _____. C. The phase shift is _____. D. Sketch 2 full periods of the graph.____. For f(x) = 1 + 2cos(x/4): A. The amplitude is ______. B. The period is ______. 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
