1. The problem statement, all variables and given/known data which best describes y=4x^3 - 3x^4 find max/min points and inflection points 3. The attempt at a solution When I work this one out I get x<0 and 0<x<1 as my two local max points. However, the book says there is only ONE max point - why is this? with the second derivative I do get two inflection points of 0 and 1/2 which I assume to be correct. Thoughts??
