Question

ater coming out from a fountain is modeled by the function f(x)= -x^8x+2 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=1 to x=4 represent
oobleck
the average rate of change represents the slope of the line joining the two points on the curve where x=1 and x=4.
