论文部分内容阅读
数学课堂教学中教师说过一次函数是初中数学最为重要的知识点,也是中考必考的知识点,所以扎实的掌握这部分知识是非常必要的。但通过与同学交流和探讨的过程中发生诸多学生并没有扎实的理解和掌握这部分知识。在此笔者将通过概述一次函数基本知识来分析一次函数图像的应用,希望能够给予学生一定的帮助。
In the mathematics classroom teaching, the teacher said that the primary function is the most important knowledge point for junior high school mathematics, and it is also the knowledge point for the examination. Therefore, it is necessary to have a solid grasp of this part of the knowledge. However, many students did not have a solid understanding and mastery of this knowledge through the process of communicating and discussing with classmates. Here, the author will analyze the application of a function image by summarizing the basic knowledge of a function, hoping to give the student some help.
