Rate of Change on Quadratic Function Between Interval

A ball is thrown into the air from the edge of a 48-foot-high cliff so that it eventually lands on the ground. the graph below shows the height, y, of the ball from the ground after x seconds. When was the ball descending?

• 0 ≤ x ≤ 2.5

• 0 < x < 5.5

• 2.5 < x < 5.5

• x ≥ 2

• r(x) because its rate of change is 4 while the rate of change for s(x) is 2 over the interval [1,3]

• r(x) because its rate of change is 3 while the rate of change for s(x) is 2 over the interval [1,3]

• s(x) because its graph appears steeper than that of r(x) over the interval [1, 3]

• Neither, both graphs appear to rise at the same rate
