What is the average rate of change in f(x) over the interval [4,13]?
mestny [16]

we know that

Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph

So

A=\frac{(f(b)-f(a))}{(b-a)}

in this problem

a=4\\ b=13\\ f(a)=f(4)=8\\ f(b)=f(13)=11

substitute the values in the formula above

A=\frac{(11-8)}{(13-4)} \\ \\ A=\frac{3}{9}

Divide by 3 both numerator and denominator

A=\frac{1}{3}

therefore

the answer is

\frac{1}{3}
