Finding the inflection points of a function
WebDec 20, 2024 · To find the inflection points, we use Theorem \(\PageIndex{2}\) and find where \(f''(x)=0\) or where \(f''\) is undefined. We find \(f''\) is always defined, and is 0 … WebSummary. An inflection point is a point on the graph of a function at which the concavity changes.; Points of inflection can occur where the second derivative is zero. In other words, solve f '' = 0 to find the potential inflection points.; Even if f ''(c) = 0, you can’t conclude that there is an inflection at x = c.First you have to determine whether the …
