An inflection point can also occur at points where f"(x) is undefined as long as the function, f(x), is continuous at that point and the concavity changes.
Note that for an inflection point to exist, f(x) must be continuous. Even if a point exists such that f"(x) = 0 or undefined, and concavity changes at that point, it is only an inflection point if f(x) is continuous at that point, as shown in the example below.
Given a graph of f'(x), it is possible to find the inflection points of f(x) based on the relationships between f(x), f'(x), and f"(x): 1. When f"(x) is positive, f'(x) is increasing, and f(x) is concave up. 2. When f"(x) is negative, f'(x) is decreasing, and f(x) is concave down. 3. When f"(x) is 0, f'(x) is not changing, and f(x) may have an infl...

May 17, 2022 · This article explains the definition of an inflection point, as well as the relationship between inflection points and concave up/concave down intervals. We also discuss how to find inflection points on a graph and how to identify inflection points in 5 steps using a table.
Dec 21, 2020 · 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 the concavity changes from up to down at x = a, f ″ changes from positive to the left of a to negative to the right of a, and usually f ″ (a) = 0.
The point where the function is neither concave nor convex is known as inflection point or the point of inflection. In this article, the concept and meaning of inflection point, how to determine the inflection point graphically are explained in detail.

Definition of an Inflection Point. Consider a function y = f (x), which is continuous at a point x 0. The function f (x) can have a finite or infinite derivative f '(x 0) at this point.
