- 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.

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 x = a, f′′ f ″ changes from positive to the left of a a to negative to the right of a a, and usually f′′(a) = 0 f ″ (a) = 0.
A point of inflection is any point at which a curve changes from being convex to being concave. This means that a point of inflection is a point where the second derivative changes sign (from positive to negative or vice versa) To find the points of inflection of a curve with equation y = f (x):
When f''<0, f ′′ <0, which means that the function's rate of change is decreasing, the function is concave down. In contrast, when the function's rate of change is increasing, i.e. f''>0, f ′′> 0, the function is concave up.
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.

An inflection point is a point where the graph of a function changes concavity from concave up to concave down, or vice versa. Since concavity is based on the slope of the graph, another way to define an inflection point is the point at which the slope of the function changes sign from positive to negative, or vice versa:
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. Now that we have all the concavity definitions out of the way we need to bring the second derivative into the mix.
