  1. Concavity review (article) | Khan Academy

    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 …

  2. Concavity - Math.net

    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 …

  3. Concave function - Wikipedia

    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 …

  4. Concavity Explained: Definition, Examples, Practice & Video Lessons

    Concavity refers to the direction in which a function curves. A function is said to be concave up when it curves upwards, resembling a cup that can hold water, and concave down when it …

  5. 3.4: Concavity and the Second Derivative - Mathematics LibreTexts

    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 …

  6. 1.4 Concavity | Precalculus - Lumen Learning

    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 …

  7. Concavity and Points of Inflection - GeeksforGeeks

    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 …

  8. Concavity - Emory University

    Being able to determine the above-described concavity (up or down) of a function on various intervals and to locate a function's points of inflection will help us in a substantial way in …

  9. Concavity - Matherama

    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 …

  10. 5.4 Concavity and inflection points - Whitman College

    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 …
