The Ferris Wheel ride at a carnival sits 3 meters above the ground and sends riders to a maximum height of 33 meters in the air. The equation y = 15sin(x) + 18
models the height of a rider with respect to the rotation of the ride and is represented as a graph in the xy-coordinate plane below.
A. The amplitude of the function is 15
B. The period of the function is 2π
C. The midline of the function is y = 15
D. The function is increasing over the interval 0 < x < π
E. The function is decreasing over the interval π/2 < x < 3π/2
