Inflection Points. An Inflection Point is where a curve changes from Concave upward to Concave downward (or vice versa) So what is concave upward / downward ? Concave upward is when the slope increases: Concave downward is when the slope decreases: Here are some more examples: Learn more at Concave upward and Concave downward. Finding where ...

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.

- Using F'(X) to Find Inflection Points
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...
