Question

Find the x and y intercepts, use derivatives to find critical numbers, inflection points, intervals of increase and decrease, intervals of concavity, and local minima and maxima. r(x)=x^3/3+x^2

Answer 1

someone tell me this is less complicated than it sounds :(

Answer 2

See http://www.khanacademy.org/math/calculus/derivative_applications/critical_points_graphing/v/minima--maxima-and-critical-points

It involves finding the first and 2nd derivatives. But the short video makes it a lot clearer on the gory details then trying to explain it with text.
