Concave interval calculator.

An inflection point only requires: 1) that the concavity changes and. 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f"(x) = 0 OR if f"(x) is undefined. An example of the latter situation is f(x) = x^(1/3) at x=0. t-interval calculator. Have a question about using Wolfram|Alpha? Contact Pro Premium Expert Support ».
