- A curve's inflection point is the point at which the curve's concavity changes. For a function f (x), f (x), its concavity can be measured by its second order derivative f'' (x). f ′′(x). When f''<0, f ′′ <0, which means that the function's rate of change is decreasing, the function is concave down.

When the second derivative is negative, the function is concave downward. And the inflection point is where it goes from concave upward to concave downward (or vice versa). Example: y = 5x 3 + 2x 2 − 3x

Dec 21, 2020 · 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 which the concavity changes from up to down or down to up; such points are called inflection points.
The point on a smooth plane curve at which the curvature changes sign is called an inflection point, point of inflection, flex, or inflection. In other words, it is a point in which the concavity of the function changes.

- 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...

Nov 16, 2022 · A point \(x = c\) is called an inflection point if the function is continuous at the point and the concavity of the graph changes at that point.
