Determine the amplitude, midline, period, and an equation involving the sine function for the graph shown below. 10 y 8 6 4 2 X 7 -6 -5 -4 -3 -2 1 2 3 4 5 6 -2 -4 -6 -8 -10 Enter the exact answers. Amplitude: A = Number Midline: y = Number Period: P = Enclose arguments of functions in parentheses. For example, sin (2 * x). Include a multiplication sign between symbols. For example, for 2 7 type in 2 * T. For the number 7, either choose 7 from the drop-down menu (under a ) or type in Pi (with a capita P). y =
