Concave downward graph.

Recall the concavity test. - If g ′′ (x) > 0 on an interval I, then the graph of g is concave upward on I. - If g ′′ (x) < 0 on an interval I, then the graph of g is concave downward on I. Therefore, in order to determine concavity we must first find g ′′ (x). Since g ′ (x) = 24 x 2 + 4 x 3, then g ′′ (x) =Calculus questions and answers.

An inflection point 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.
