近几年高考数学的压轴题很多都涉及多个参变量的函数综合题,主要考查函数的单调性,函数的零点与极值(最值),求参变量的取值范围及相关不等式的证明.同学们处理这一类问题相当困难,特别是对涉及多个参变量的函数综合题感到很棘手,现介绍一些常用的处理方法与技巧,供大家参考.1.求参变量的取值范围求参变量的取值范围通常通过分离变量,转化为求新函数的值域,也可以等价变换,通 In recent years, many college entrance examination mathematics finale questions involve a number of parameters of the comprehensive function of the test questions, the main test of monotonicity, zero and extreme function (most value), the parameter range and the inequality of the proof Students to deal with this type of problem is quite difficult, especially for a comprehensive function involving multiple parameters of the variables is very tricky, are introduced some commonly used methods and techniques for your reference.1. Find the range of parameters Seeking the range of the value of the variable is usually through the separation of variables into a new function value range, can also be equivalent to transform, pass
