函数概念一直处于数学的核心位置,数学中的许多概念由函数派生、由函数统领,德国数学家克莱因称函数为数学的灵魂。如今函数概念几乎渗透到每一个数学分支,函数是刻画事物运动变化的重要工具,是使学生形成数学与客观世界的联系的认识。在高中数学教学中,函数作为基本数学思想和重要解题方法,贯穿
The concept of function has always been at the core of mathematics. Many concepts in mathematics are derived from functions and are guided by functions. The German mathematician Klein claims that the function is the soul of mathematics. Nowadays the concept of function permeates almost every branch of mathematics. Function is an important tool to describe the change of the movement of things. It is to make students understand the relationship between mathematics and the objective world. In high school mathematics teaching, the function runs through as the basic mathematics thought and the important solution method
