What is the absolute extrema of the given function on the interval[−1,1]? f(x) = x3- 2x2+ x Point of Extrema: Ify=f(x)is a curve equation then the points of relative extrema are found at the solutions to the equationf′(x)=0. ...
Existence of global extrema(全局极值的存在性):Let Ω be acompact set(闭合且有界)and let f be continuous on Ω. Then the global extrema of f over Ω exist. A set\Omega\subset R^{n}is said to beclosedif it contains all the limits of convergent sequences of points in Ω. A s...
