   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) + +.

   Dec 21, 2020 · 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.

   If a function changes from concave upward to concave downward or vice versa around a point, it is called a point of inflection of the function. In determining intervals where a function is concave upward or concave downward, you first find domain values where f″ (x) = 0 or f″ (x) does not exist.

   How do you know if a function is concave upward?

   • A function is said to be concave upward on an interval if f″ (x) > 0 at each point in the interval and concave downward on an interval if f″ (x) < 0 at each point in the interval. If a function changes from concave upward to concave downward or vice versa around a point, it is called a point of inflection of the function.

   What does a concave function look like?

   • Likewise, a function that is concave downward on an interval looks like a portion of a parabola that opens downward. If the graph of a function is linear on some interval in its domain, its second derivative will be zero, and it is said to have no concavity on that interval.

   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 if a graph of a function has no concavity?

   • If the graph of a function is linear on some interval in its domain, its second derivative will be zero, and it is said to have no concavity on that interval. Example 1: Determine the concavity of f (x) = x3 − 6 x2 −12 x + 2 and identify any points of inflection of f (x). Because f (x) is a polynomial function, its domain is all real numbers.

   Is f g a concave function?

   • where the first inequality holds since f is concave and g increasing, and the second inequility follows from g being concave. We have thus proved that Thus, (f ◦ g) is a concave function. (with a similar proof for convexity.) Remark 10. An increasing transformation of a concave (convex) function is not necessarily concave (convex).

   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. Concave up.
