函数是初中数学的一个重要组成部分,它包括一次函数、反比例函数和二次函数.在学习函数之前,初中数学主要讨论的是静态数学问题,引入函数概念后,静态到动态的转变将使教学内容与方式均发生了较大转变.理解、掌握及运用函数是对学生的三个基本要求,通过对函数及函数图象的运用能使中学生更深刻体会到数形结合的思想方法.通过基本初等函数的学习,中学生的数学知识体系将得到较大的提升,数学思维更加更加
Function is an important part of junior high school mathematics, which includes a function, inverse function and quadratic function.In the study of function, junior high school mathematics is mainly discussed the problem of static mathematics, the introduction of function concept, the static to dynamic transformation will make teaching Content and manner have undergone a major change.Comprehension and use of the function is the three basic requirements for students through the use of the function and function of the image can make students more deeply understand the combination of number and shape of the way of thinking through the basic Elementary function learning, middle school students mathematical knowledge system will be greatly improved, mathematical thinking more
