Question

Let f(x)=5x^1/3+x^2. For what values of x does the instantaneous rate of change equal when the average rate of change is 3.119? <--- HELP!!!

Answer 1

You need to find the derivative of called it f'(x)

Answer 2

\[f'(c)=\frac{f(b)-f(a)}{b-a}=3.119\]
we have something like this a,b,c are all values of x
