本文从抽象函数与不等式、二次函数与不等式、几何中函数问题与不等式等方面来阐述函数与不等式的综合应用.一、抽象函数与不等式的综合应用抽象函数型综合问题,一般通过对函数性质的代数表述,综合考查数学符号语言的理解和接受能力,对函数性质的代数推理和论证能力,对一般和特殊关系的认识能力.例1设函数f(x)定义在R上,对任意
This paper expounds the comprehensive application of function and inequality from the aspects of abstract function and inequality, quadratic function and inequality, geometric problem of function and inequality, etc .. First, the comprehensive application of abstract function and inequality Abstract function-based synthesis problem, Algebraic expression, a comprehensive examination of the mathematical symbolic language understanding and acceptability, the nature of the function of algebraic reasoning and argumentation ability, general and special relationship knowledge ability.Example 1 Let the function f (x) defined on the R
