一种判断多项式函数极值点和拐点个数的简单方法

摘要

A simple method for determining the numbers of extreme points and inflexion points of a class of polynomial function is given. Some relative results are gained, and the validity and convenience of the method are verified through some typical examples.%给出了判断一类多项式函数极值点和拐点个数的一种快捷方法，得到了几个相关结论，并通．过几个典型例题验证了该方法解题的有效性和快捷性．
