- 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.

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): Examiner Tip.
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.

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 \(f''(a)=0\).
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. In contrast, when the function's rate ...
Definition: A function f is described to be Concave Up on the interval (a, b) if the slopes of the tangent lines from a to b are increasing, that is if x, y ∈ (a, b) where x < y, then f′(x) < f′(y).
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:
