Water coming out from a fountain is modeled by the function f(x) = −x2 + 8x + 2 where f(x) represents the height, in feet, of th

andrew-mc [135]

$f(x)=-x^{2} +8x+2$
Average rate of change from x = 1 to x = 4 = $\frac{f(4)-f(1)}{4-1}= \frac{( -4^{2}+8(4)+2)-(- 1^{2}+8(1)+2)}{3}= \frac{(-16+32+2)-(-1+8+2)}{3}= \frac{18-9}{3}=$ $\frac{9}{3}=3$

This means that the water rises up with an average speed of 3 feet per second from 1 second to 4 seconds
