函数知识是我们初中的一个重要知识点,也是初中数学知识的重要考点,与其他数学知识相衔接,比如方程、不等式等。初中学生刚开始接触函数部分,所以,必须学习好初中函数部分,为以后的函数学习做一个好的铺垫。初中函数的学习要注重函数图象的运用,数学函数图象优点颇多,是一种重要的思想方法,其有利于数学问题的解决。本篇文章就针对初中数学函数图象与性质做了一个详细的教学研究。
Function knowledge is an important knowledge point of our junior high school and an important test point of junior high school mathematics knowledge. It connects with other mathematical knowledge, such as equations, inequalities and so on. Junior high school students have just started to touch the function part, so, must learn good junior high school function part, make a good bedding for future function study. The function of the middle school should pay attention to the use of the function image. The advantage of the mathematical function image is an important way of thinking, which is conducive to the solution of mathematical problems. This article makes a detailed teaching research on the image and nature of junior high school math functions.
