WEBInflection points are points where the function changes concavity, i.e. from being "concave up" to being "concave down" or vice versa. They can be found by considering where the second derivative changes signs. In similar to critical points in the first derivative, inflection points will occur when the second derivative is either zero or undefined.

Inflection point - Wikipedia
https://en.wikipedia.org/wiki/Inflection_point
WEBDefinition. Inflection points in differential geometry are the points of the curve where the curvature changes its sign. [2] [3] For example, the graph of the differentiable function has an inflection point at (x, f(x)) if and only if its first derivative f' has an isolated extremum at x. (this is not the same as saying that f has an extremum).

Analyzing the second derivative to find inflection points - Khan Academy
https://www.khanacademy.org/math/ap-calculus-ab/ab-diff-analytical-applications-new/ab-5-6b/a/review-analyzing-the-second-derivative-to-find-inflection-points
WEBWe can find the inflection points of a function by analyzing its second derivative. Example: Finding the inflection points of f ( x) = x 5 + 5 3 x 4. Step 1: Finding the second derivative. To find the inflection points of f , we need to use f ″ : f ′ ( x) = 5 x 4 + 20 3 x 3 f ″ ( x) = 20 x 3 + 20 x 2 = 20 x 2 ( x + 1)

Point of Inflection - Calculus
https://www.radfordmathematics.com/calculus/Differentiation/point-of-inflection/point-of-inflection.html
WEBA point of inflection, or point of inflexion, is a point along a curve y = f(x) at which its concavity changes; it goes from being: concave up, f ″ (x) > 0, to concave down, f ″ (x) < 0, or. concave down, f ″ (x) < 0, to concave up, f ″ (x) > 0 . For the second derivative to change sign it has to go through zero, f ″ (x) = 0 .

Inflection Points | Brilliant Math & Science Wiki
https://brilliant.org/wiki/inflection-points/
WEBSummary. 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.

WEBAn inflection point occurs when the sign of the second derivative of a function, f" (x), changes from positive to negative (or vice versa) at a point where f" (x) = 0 or undefined. Thus, the process for determining the inflection points of a function are as follows: Compute the second derivative of the function.
