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 …

Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is …

Dec 21, 2020 · We have identified the concepts of concavity and points of inflection. It is now time to practice using these concepts; given a function, we should be able to find its points of inflection and …

In mathematics, a concave function is one for which the function value at any convex combination of elements in the domain is greater than or equal to that convex combination of those domain …

A function that increases can be concave up or down or both, if it has an inflection point. The increase can be assessed with the first derivative, which has to be > 0. The concavity is assessed with the …

Jul 23, 2025 · Concavity in a curve refers to its curvature, or the way it bends. If a curve is concave up, it opens upward like a cup, while if it's concave down, it opens downward like a frown.

Learn concavity and points of inflection in calculus using second derivatives. Clear definitions, step-by-step worked examples, graphs, and practice problems for students.

A function’s concavity describes how its graph bends—whether it curves upwards like a bowl or downwards like an arch. Previously, concavity was defined using secant lines, which compare the …

Concavity tells us the shape and how a function bends throughout its interval. When given a function’s graph, observe the points where they concave downward or downward. These will tell you the …

Fortunately, there is a simple connection between the concavity of a function and its second-derivative: Let $f$ be a function that is differentiable on some open interval containing $c$. Then, if $f'' (c) \lt 0$, …
