Hi, can someone help me guide me on how to find inflections? I am not too sure how to do it in such a problem as the follows: 1. The problem statement, all variables and given/known data Determine a, b, and c so that the function f(x) = x^3 + ax^2 + bx + c has critical points at (1,5) and an inflection point at (2,3) 2. Relevant equations 3. The attempt at a solution I am not too sure how to persue this, for critical points I know the derivative needs to equal zero and then you find the critical points that way, but I dont know what to do for the inflection. Thank You!
