WebMar 26, 2016 · Make a sign graph, as shown here. Because the concavity switches at x = 1 and because. equals zero there, there's an inflection point at x = 1. Find the height of … WebAn inflection point only requires: 1) that the concavity changes and. 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f" (x) = 0 OR if f" (x) is undefined. An example of the latter situation is f (x) = x^ (1/3) at x=0.
