Graph the following for at least one cycle and lable the five key points a. y = 2 cos (2x)
b. y = - sin (x- pi/4) +2

()1. how do you find range? 2.the following set of data is to be organized into a histogram. if there are to be five intervals on the graph, what should the length of each interval be? 30, 34, 23, 21, 27, 25, 29, 29, 25, 23, 32, 31

Need on this geometry question. explain how you did it.
