How do you find critical points

WebA critical point is an inflection point if the function changes concavity at that point. The function has a critical point (inflection point) at The first and second derivatives are zero at. Figure 6. Trivial case: Each point of a constant function is critical. For example, any point of the function is a critical point since. WebSep 6, 2024 · If you define a critical point of a function f to be a point where f ′ ( x) = 0, then the function f: ( − ∞, 3) ∪ ( 3, ∞) → R defined by f ( x) = x + 1 x − 3 does not have a critical point since f ′ ( x) < 0 for every x in its domain.
