抽象函数问题,是指没有给出函数的解析式,只给出函数具有的某些特征,求此函数应具有的其它特征的问题.由于高一学生只熟悉一些具体函数,如一次函数、二次函数、正比例函数、指数函数、对数函数等,对抽象函数不够了解,没有具体的函数模型和解题方法可供参考.因此,学生对求解抽象 The problem of abstract function refers to the problem of not giving the analytical expression of the function and only giving some features of the function and finding the other characteristics that the function should have.As a result, students in higher school are only familiar with some specific functions, Function, proportional function, exponential function, logarithm function, etc., do not know enough about abstraction function, there is no concrete function model and solving method available for reference.Therefore,
