我们对函数已经形成了初步的认识,反比例函数是最基本的函数之一.类比一次函数及正比例函数的学习,我们要从具体问题中加深对反比例函数概念的理解,加强对其图像与性质的认识与掌握,建立反比例函数模型分析、解决简单的实际问题,从而进一步理解函数的内涵并感受函数的数学模型思想,为后续各类函数的学习打好基础.【学习目标1】理解反比例函数的意义一般地,如果两个变量x,y之间的关系 We have formed a preliminary understanding of the function, the inverse proportion function is one of the most basic function of the analogy of the one-way function and the study of the proportional function, we need to deepen the understanding of the concept of the inverse proportion function from the specific problems, to strengthen its image and nature Understanding and mastery, the establishment of inverse proportional function model analysis, to solve simple practical problems, so as to further understand the meaning of the function and feel the mathematical model of the function ideas for the follow-up of various types of function to lay the foundation for learning 【Learning Objective 1】 Understanding the inverse proportion function Meaning Generally, if the relationship between two variables x, y
