The average rate of change of the function over the given interval is 9

Here, we want to calculate the average rate of change of the function within the given interval

Mathematically, given a function f(x) , the average rate of change of the function within the interval a ≤ x ≤ b is given below;


\frac{f(b)\text{ - f(a)}}{b-a}

withe respect to this question;

a = 1

b = 4

f(a) = f(1) = 12

f(b) = f(4) = 39

The average rate of change within the given interval is thus;


(39-12)/(4-1)\text{ = }(27)/(3)\text{ = 9}
