Homework Statement
the max value of f(x)=x^3(40-x^2) on the closed interval 0<= x <= 40 occurs at x=?
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 I am not so sure...
