(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

the max value of f(x)=x^3(40-x^2) on the closed interval 0<= x <= 40 occurs at x=?

3. The attempt at a solution

different problem, same story (notes are unclear, and the book only complicates things more). I know the answer is 24, but this will not help me on the final exam!

Can someone please provide a more clear explanation of what the book is asking? What would be the first step to determine the max value of x given the above constraints? thanks!

* i knwo i have to take the derivative of the equation, other than that im not so sure...
