抽象函数是指没有给出具体表达式,规定了若干逻辑规则的函数。近几年的全国各地高考中都出现了有关抽象函数的试题,主要考查考生的抽象思维能力、分析问题能力及创新能力。抽象函数是高中数学函数部分的难点,也是高中与大学函数部分的衔接点。本文主要浅谈了中学数学中常见的抽象函数问题的解题策略。一赋值策略处理抽象函数问题最基本的策略是赋值法。赋值规律一
An abstract function refers to a function that does not specify a specific expression and that specifies a number of logical rules. In recent years, college entrance examination all over the country have appeared on the abstract function of the test questions, mainly examine the candidate’s abstract thinking ability, problem-solving ability and ability to innovate. Abstract function is a difficult part of high school mathematics function part, also is the connection point of high school and university function part. This article mainly talks about the common problems of solving abstract problems in middle school mathematics. A assignment strategy The most basic strategy for dealing with abstract function problems is assignment. The law of assignment one
