Webmaximum values. That is, extrema are the points of a function where it is the largest and the smallet. We can identify two types of extrema - local and global. Global extrema are the largest and smallest values that a function takes on over its entire domain, and local extrema are extrema which occur in a speciﬁc neighborhood of the function. WebIn other words, local extrema can only occur at critical points. Note this theorem does not claim that a function [latex]f[/latex] must have a local extremum at a critical point. Rather, it states that critical points are candidates for local extrema. For example, consider the function [latex]f(x)=x^3[/latex].

WebMar 26, 2016 · Now, plug the three critical numbers into the second derivative: At –2, the second derivative is negative (–240). This tells you that f is concave down where x equals –2, and therefore that there’s a local max at –2. The second derivative is positive (240) where x is 2, so f is concave up and thus there’s a local min at x = 2. eagle river falcons facebookWebMar 3, 2024 · This calculus video tutorial explains how to find the local maximum and minimum values of a function.
