抽象函数是高考的一个知识点.在每年的高考中,不管是全国卷,还是各省市单独命题的试卷中,都不同程度的出现过抽象函数问题.随着新课程的实施,抽象函数问题在理科的试卷中出现的力度不断加大.那么,什么样的函数为抽象函数呢?没有给出函数关系式的函数为抽象函数.由于抽象函数没有具体的函数关系式,所以很多学生面对它时无从下手.为此,我根据自己多年的教学经验谈谈对抽象函数问题的解题方法. Abstract function is a knowledge point of college entrance examination in the annual college entrance examination, whether it is the national volume, or a separate proposition papers in various provinces and cities, have varying degrees of abstraction function problems.With the implementation of the new curriculum, abstract function problems Science papers appeared in the intensity continue to increase.So, what kind of function is an abstract function? Function function is not given an abstract function as abstract function does not have a specific function relationship, so many students face it When no one can start .To this end, I based on my years of teaching experience to talk about the abstract function problem solving method.
