Ok so I get how to find the critical points but I don't understand how you tell if it's mmaximum, minimum, or point of inflection. Say I have one point (-2,-16), what would it be?
One more small item ... you understand that determining what you want answered will most probably require analysis using the second derivative, a calculus topic?
no this is from precalc class. The original question is f(x) = x^2 + 4x -12 and I'm supposed to find the critical points for the function and determine whether each point is a maximum, minimum, or point of inflection. I found the critical point to be (-2,-16).
