近年来 ,经常在高考、高考模拟以及竞赛中出现与抽象函数有关的试题 .一般地 ,抽象函数是指没有给出具体的函数解析式 ,只是给出函数所具有的某些性质的函数 .这类试题往往概念抽象、隐蔽性强、灵活性大、综合程度高 ,因此 ,学生常常感到难以掌握 .本文主要介绍求解抽象函数问 In recent years, examination questions related to abstract functions often appear in college entrance examinations, college entrance examination simulations, and contests. In general, an abstract function means that no concrete function analytical expression is given, but only some functions of the function are given. Class questions are often conceptually abstract, covert, flexible, and highly integrated. As a result, students often find it difficult to master. This article mainly introduces solving abstract functions.
