Inflection 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.

The second derivative tells whether the curve is concave up or concave down at that point. If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly, if the second derivative is negative, the graph is concave down. This is of particular interest at a critical point where the tangent line is flat and ... We say this function f f is concave up. Figure 4.34(b) shows a function f f that curves downward. As x x increases, the slope of the tangent line decreases. Since the derivative decreases as x x increases, f ′ f ′ is a decreasing function. We say this function f f is concave down. 1.
