I have a concavity question and my work. I'm having some trouble finding the absolute maximum.
I took the derivative and found the absolute minimum at -1. Are you supposed to take the second derivative to get the absolute max? I also tried to factor the derivative but was unsuccessful.Code:let f(x)=x^3-(3/2)x^2 on the interval [-1,2]. Find the absolute maximum and absolute minimum of f(x) on this interval.
anyone remember doing this?
