     • The concavity of the graph of a function refers to the curvature of the graph over an interval; this curvature is described as being concave up or concave down. Generally, a concave up curve has a shape resembling "∪" and a concave down curve has a shape resembling "∩" as shown in the figure below.

   How do you find the concavity of a function?

   • At these points, the sign of f" (x) may change from negative to positive or vice versa; if it changes, the point is an inflection point and the concavity of f (x) changes; if it does not change, then the concavity stays the same. Given these facts, we can now put everything together and use the second derivative of a function to find its concavity.

   What is a concavity interval?

   • Concavity intervals are intervals where the curve of a function is either concave upward or concave downward. They are necessary to determine the critical points of a function and to solve optimization problems. Can I use this calculator for any function?

   How do you find the concavity of a graph?

   • To determine its concavity, we follow these steps: Since the second derivative f′′(x) f ′ ′ (x) equals 2 2, it is greater than zero for all x x. This means that the function f(x) = x2 f (x) = x 2 is concave up everywhere, which means that its graph opens upward.

   Why do we need to know where a graph is concave?

   • If we are trying to understand the shape of the graph of a function, knowing where it is concave up and concave down helps us to get a more accurate picture. Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points.

   How do you know if a function is concave?

   • In mathematical terms, a function f(x) f (x) is concave up on an interval if the second derivative f′′(x) f ′ ′ (x) is positive at each point of the interval and concave down if it is negative at each point of the interval. If none of the conditions are met, the function is considered neither concave up nor concave down on that interval.

   Given any x 1 or x 2 on an interval such that x 1 < x 2, if f (x 1) > f (x 2), then f (x) is decreasing over the interval. In the graph of f' (x) below, the graph is decreasing from (-∞, 1) and increasing from (1, ∞), so f (x) is concave down from (-∞, 1) and concave up from (1, ∞).
