Example: y = x 3 − 6x 2 + 12x − 5. The derivative is: y' = 3x 2 − 12x + 12. The second derivative is: y'' = 6x − 12. And 6x − 12 is negative up to x = 2, positive from there onwards. So: f (x) is concave downward up to x = 2. f (x) is concave upward from x = 2 on. And the inflection point is at x = 2: Calculus Index.

In differential calculus and differential geometry, an inflection point, point of inflection, flex, or inflection (rarely inflexion) is a point on a smooth plane curve at which the curvature changes sign.
May 17, 2022 · This article explains the definition of an inflection point, as well as the relationship between inflection points and concave up/concave down intervals. We also discuss how to find inflection points on a graph and how to identify inflection points in 5 steps using a table.
Summary. A curve's inflection point is the point at which the curve's concavity changes. For a function \ (f (x),\) its concavity can be measured by its second order derivative \ (f'' (x).\) When \ (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 ...
