simple SIMPLE local extremia question 1. The problem statement, all variables and given/known data Find the absolute maximum and absolute minimum values of f(x) = 3x^4 - 8x ^3 + 12x^2 -48x +25, where 0 <= x <= 3. 2. Relevant equations N/a 3. The attempt at a solution f'(x) = 12x^3 - 24x^2 + 24x -48 = 12 (x^3 - 2x^2 + 2x -4) = 12 (x-2) (X^2 +2) I know how to do the rest, but just wondering before I go on... What should i do with that one factor...do I omit the (x^2 +2)?
