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 …

What is concavity? Concavity relates to the rate of change of a function's derivative. A function f is concave up (or upwards) where the derivative f ′ is increasing. This is equivalent to the …

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 …

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 …

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 …

The definition of the concavity and point of inflection of the graph of a function are presented. Several examples with detailed solutions are also included.

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 …

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 …

To determine the concavity of f (x),recall that f (x) is concave up when f (x) is increasing and f (x) is concave down when f (x) is decreasing. From the graph, we see that f (x) is increasing on …

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 …
