Question 10

On a coordinate plane, a curve crosses the y-axis at (0, negative 1) and then increases to 1 at pi. On a coordinate plane, a curve crosses the y-axis at (0, 0.5) and then decreases to 1 before pi. On a coordinate plane, a curve crosses the y-axis at (0, 0) and then increases to 1. It then decreases and crosses the x-axis at pi.
