Determine the amplitude, midline, period, and an equation involving the sine function for the graph shown below. Enter the exact answers. Amplitude: A = Number Nlidllne: y = Number Period: P = @ El Enclose arguments of functions in parentheses. For example, 5111(2 * 3:). Include a multiplication sign between symbols. For example, for 2 7r type in 2 * a". For the number 11', either choose 1r from the drop-down menu (under a) or type in Pi (with a capital P). 3;: @E3
