WebRather, it states that critical points are candidates for local extrema. For example, consider the function [latex]f(x)=x^3[/latex]. We have [latex]f^{\prime}(x)=3x^2=0[/latex] when [latex]x=0[/latex]. Therefore, [latex]x=0[/latex] is a critical point. WebClassifying critical points All local extrema are critical points. Not all critical points are local extrema. Often, they are saddle points. Now it's time to classify critical points, and 855 Math Teachers 15 Years on market
