WebWe now know how to determine where a function is increasing or decreasing. However, there is another issue to consider regarding the shape of the graph of a function. If the graph curves, does it curve … 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.
