how to determine and graph the amplitude,period, frequency, and phase shift of each equations :
A) y=2sin(pi/3(x-2))-4
amplitide:: 2
period:: (2pi)/(pi/3) = 6
freq = (1/6) cycle per sec.
phase shift = c/a = 2/2 = 1
Graph::

=====================
B) Y= -4+2cos(pi/3(x-3.5))
anplitude:: 4
period:: (2pi)/(pi/3) = 6
freq:: 1/6 cycle per sec
phase shift:: c/a = 3.5/2 = 7/4
Graph::
