函数是高中数学中非常重要的内容之一,是贯穿整个高中数学学习,乃至一生的数学学习过程中的。其重要性体现在:1、函数本源于现实生活,具有广泛的应用。2、函数本身是数学的重要内容,是沟通代数、几何、三角等内容的桥梁。也是今后进一步学习高等数学的基础方法。3、函数部分内容蕴 Function is one of the most important elements in high school mathematics. It is a process of mathematics learning throughout the entire high school mathematics learning and even a lifetime. Its importance is reflected in: 1, the function originates from real life, has a wide range of applications. 2, the function itself is an important part of mathematics, is to communicate algebra, geometry, triangle and other content of the bridge. It is also the basic method for further study of advanced mathematics in the future. 3, the contents of the function section Yun
