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