Using the smallest possible horizontal shift, find an equation for the graph below in terms of: 

Periodic curve, x axis scaled from negative 2 pi to 2 pi, 4 visible turning points, first at (negative 5 fourths pi, comma negative 1), second at (negative 3 fourths pi, comma 3), y intercept between 0 & negative 1.

  1. Draw in the mid-line and max and min lines. Then determine the amplitude, period, and shifts.
