以函数为载体,以导数为工具,以考查函数性质及导数应用为目标是最近几年函数与导数交汇试题的显著特点和命题趋向,运用导数确定参数的取值范围是一类常见的探索性问题.本文,笔者借用一道导数联考题,给出五种确定参数取值范围的求解方法:一阶导数后放缩求解、分离参数法、使用充分条件、二阶导数、先求极限后证明. Using function as a carrier and derivative as a tool to test the properties of the function and the application of derivative as the objective is the salient features and proposition tendency of the intersection of function and derivative in recent years. Using the derivative to determine the range of the parameter is a kind of common exploratory This article, I borrow a derivative test questions, given five solutions to determine the range of parameters: scaling after the first derivative solution, separation of parameter method, the use of sufficient conditions, the second derivative, first after the limit proved.
