课改新教材中引入了全称量词与存在量词,刚开始入手的时候,笔者感觉这块内容比较简单,只是在判定含有这两类量词的命题的真假上稍难一些,然而随着这些量词慢慢渗透到函数的最值尤其是含参数的函数的值域与不等式、方程结合的问题中,此类问题一跃成为高考命题中的热点与难点,尤其是同时含有两个量词的方程与不等式就更加难以解决.下面我们就通过一些例子来找到解决这种类型问题的一些途径.一、含两类量词的不等式的解法 At the beginning of the course, the author introduced this simple textbook which introduced the full quantifier and existential quantifier. However, as the content of this book was relatively simple, it was a little harder to judge the true or false of the propositions containing these two types of measure words. However, Slowly penetrate to the value of the function, especially with the value of the parameter function range and inequality, the problem of combining equations, such problems became the hot and difficult point in the college entrance examination proposition, especially with both two-word equation and Inequality is even more difficult to solve. Here are some examples to find some ways to solve this type of problem. First, with two types of quantifiers inequality solution
