- 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.

Definition 1. A function f : S ⊂ Rn → R defined on a convex set S is concave if for any two points x1 x2 ∈ , S and for any λ ∈ [0, 1] we have: λx1 (1 − λ) x2 ≥ λf(x1) (1 − λ)f(x2) + +. is called strictly concave if for any two points x1 , x2 ∈ S and for any λ ∈ (0, 1) we have: λx1 (1 − λ) x2 > λf(x1) (1 − λ)f(x2) + +.
In this explainer, we will learn how to determine the concavity of a function as well as its inflection points using its second derivative.
Concavity and convexity. It is said that a function f (x) is convex if, once having joined any two points of the graph, the segment stays over the graph: In this graph we can observe different segments (with different colors) that join two points of the graph and stay over it.
Review your knowledge of concavity of functions and how we use differential calculus to analyze it.
Definition. Concavity describes whether a graph opens upward (concave up) or downward (concave down). It indicates whether the graph is curving upwards like an "U" shape or downwards like an "n" shape.
