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 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?

find the slope of the for the average rate of change between x = 1 and x= 4 1st step is find the value of f(1) then F(4) the the average rate of change is \[avg ~rate~of~change = \frac{f(4) - f(1)}{4 - 1}\] then read the answer choices to see which matches
