6) concept of function
函数的概念
1.
The concept of function as well as its method of thinking has become one of major points of mathematics teaching in middle school.
本文在前人的研究基础上,从函数的概念出发,以问卷的形式调查初中学生和高中学生对函数的理解,并将此结果与函数的历史发展过程加以对比,结果表明:学生给出的定义包含了自莱布尼兹到布尔巴基学派期间诸多数学家的定义。
补充资料：函数图象
函数图象比较难定义，但可以如下描述：
在平面直角坐标系上，x轴上的值通过一定的法则得到它的函数与y轴上的值对应，这个两个值在平面直角坐标系上占有惟一的一个交点，由于x轴上与y轴上对应的坐标有无限个，这些函数的交点的集合就是此函数的图象
在解决函数问题时利用函数图象能够使复杂的函数看起来更直观,有利于对题目的理解与解答.(即数形结合)
