函数贯穿于中学数学的整个教学过程中,是数学教学的重要组成部分,函数在解题上的应用也非常广泛,其既是高考的重要考点,也是学生解答问题的重要思路。鉴于函数的重要性,有必要对其进行细致的研究,优化教学。就函数的对称性进行一定探究。 The function runs through the entire teaching process of middle school mathematics and is an important part of mathematics teaching. The function is also widely used in solving problems, which is not only an important test point for college entrance examination, but also an important way for students to answer questions. In view of the importance of the function, it is necessary to study it carefully and optimize the teaching. On the symmetry of the function to explore.
