Question 13: (3 points) Determine the amplitude, midline, period, and an equation involving the sine function for the graph shown below. 10 5 -4 3 -2 -1 -2 1 2 3 4 -10 -12 Enter the exact answers. Amplitude: A = Midline: y = 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 * J. For the number 7, either choose 7 from the drop-down menu (under o) or type in Pi (with a capital P). y =
