It says to "Determine the amplitude, period, and phase shift of each function, and then graph them." But when I get to the phase shift of the problem, it is -4/2Pi, and the E.P. is 1-2Pi? How would I express 1 - 2Pi. if I'm even doing it right -_- Thanks!

E.P. is the end point.

Hi. I teach trig in high school. Your phase shift is right on, but I'm not sure what E.P. represents. I assume you're looking for the period? With the 2 factored out of the "innards", you get 2(pi*x + 2) meaning that the period coefficient is pi. Period = 2pi/b with b representing the period coefficient. Therefore, Period = 2pi/pi....Period = 2. Shift the graph to the left 2 and make one cycle 2 units long. Hope that helps.
If you're looking for the endpoint of the first cycle and you start a cycle at -2 (moved to the left 2), and your period is 2 units in length, then the endpt of the first cycle would be -2 + 2 = 0. is that better?
