Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bars. What are the midline, amplitude, and period of this function? Graph shows a sinusoidal function plotted on a coordinate plane. A curve enters quadrant 3 at (minus 2pi, minus 3.5) and goes through (0, minus 0.5) and (2pi, minus 3.5). The midline is . The amplitude is . The period is .
