- Inflection Point -- from Wolfram MathWorld
An inflection point is a point on a curve at which the sign of the curvature (i e , the concavity) changes Inflection points may be stationary points, but are not local maxima or local minima For example, for the curve y=x^3 plotted above, the point x=0 is an inflection point
- Is $x=0$ an inflection point? - Mathematics Stack Exchange
For an inflexion point, the only thing you need to find is whether concavity changes, i e if f" (x)=0, and you specifically test if there is a change in sign in f" (x)=0
- Inflection Points - Math is Fun
At x=0, the second derivative is 0, but it is concave upward on both sides, so there's no inflection point! An Inflection Point is where a curve changes from Concave upward to Concave downward (or vice versa) So what's concave upward downward ?
- Point of Inflection - Calculus
Given a curve y=f (x), a point of inflection is a point at which the second derivative equals to zero, f'' (x)=0, and across which the second derivative changes sign

Notice that f ″ (x) changes sign at x = 1, x = 0, and x = 1, however, x = 0 is not in the domain of f and cannot correspond to an inflection point Therefore, (1, 8) and (1, 8) are the only inflection points of f
