Use this box to plot the 5 quadrantal points in their transformed positions. Now, sketch in the curve. Note that the portion in the box can be repeated to graph as many periods as you need. 3. Given the function f(x) = 3 cos(2x-)-1, graph at least two complete periods of the function. Be sure to label the tick marks appropriately. Note that the function is the same as in the first example, except "sin" is replaced with "cos." Therefore, the process is exactly the same up until we plot the 5 quadrantal points. We would have the same box, but different points. Plot the five points and then connect them. Use this box to plot the 5 quadrantal points in their transformed positions. Now, sketch in the curve.
