FOLLOW INSTTUCTIONS AND LABEL GRAPH CORRECTLY

6. (15 pts) Determine the amplitude, period, phase shift, vertical shift, and range for the function. Sketch (accurately!) ONE cycle of the graph and label the "five key points" (as in the HW and lecture) For full credit, remember: plan your graph and shape matters! You must show how you find the coordinates of your points. Without work = half credit. (hint: remember to rewrite the function to show the "true" phase shift, double check!) f(x) = -2cos Ex - - 1
