$1.00 Cosine graphing??
y = 2cos(4x + ((4pi)/(3))) + 1 Please name the amplitude, period, phase shift, x-int(s), y-int, increasing interval(s), max/min points. Also graph on a 2pi scaled graph. Also, please explain how to figure out the original equation (in this case, "2cos(4x + ((4pi/3))) + 1") if you were only given the graph.
