Question

Water coming out from a fountain is modeled by the function f(x) = -x2 + 5x + 4 where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds.

What does the average rate of change of f(x) from x = 3 to x = 5 represent?

The water falls down with an average speed of 3 feet per second from 3 seconds to 5 seconds.
The water falls down with an average speed of 5 feet per second from 3 seconds to 5 seconds.
The water travels an average distance of 3 feet from 3 seconds t

Answer 7

f(x) represents the height and x represents time.
Average rate of change of f(x) from x = 3 to x = 5 is: { f(5) - f(3) } / (5 - 3) =
{ f(5) - f(3) } / 2. Calculate this.
Numerator is height (or distance) and the denominator is time. Distance / time is speed.
With this information you can pick the correct answer.
