高考试题中,函数与不等式有很多交集,因为这类题目涉及的知识点多,方法灵活多样,综合性强,具有很好的区分度,可以有效地考查学生分析问题、解决问题的能力,倍受命题者的青睐.纵观近几年高考中的函数与不等式综合题,有不等式恒成立、能成立求参数范围的问题,也有证明不等式成立的问题.有的试题虽然考查不等式问题,但可以转化为函数的最值问题.本文针对“对任意的x∈D,f(x)≥g(x)恒成立”这一类问
There are a lot of intersection of function and inequality in the college entrance examination exams. Because such topics involve many points of knowledge, the method is flexible and diverse, comprehensive and has a good degree of discrimination, which can effectively examine students’ ability to analyze and solve problems. By the proponents of the favor.From the recent years college entrance examination in the function and inequality synthesis of questions, there are inequalities established, can establish the parameters of the scope of the problem, but also to prove that the inequality of the problem.Some questions although the test of inequality, but can Into the function of the most value problem. In this paper, for the "arbitrary x ∈ D, f (x) ≥ g
