函数概念及表示方法这部分内容在高考中占有非常重要的地位,考查的知识点不是很难,但知识点的范围却比较广,包括构成函数的要素,求简单函数的定义域和值域,以及有关映射的概念.学生们在平常的学习过程中,也要多了解一些简单的分段函数,还要会选用合适的方法来表示函数.函数概念及表示方法是函数部分的基础知识,主要以概念和函数的三要素及表示方法为主.近年来,函数的图象、分段函数也成为了高考考查的
Function concept and representation This part of the contents occupy a very important position in the college entrance examination, the knowledge of the test is not difficult, but the scope of the knowledge point is relatively wide, including the elements that constitute the function, the definition of domain and range of simple functions, As well as the concept of mapping.Students in the usual learning process, but also to understand some simple piecewise function, but also will choose the appropriate method to represent the function.Function concept and presentation method is the basic part of the function, the main The concept and function of the three elements and representation of the main.In recent years, the function of the image, the segmentation function has become a college entrance examination
