函数知识是中学数学的核心内容,也是初中数学的重要内容.教材一般安排在“数与代数”板块中的函数,包括一次函数、二次函数、反比例函数(以下简称“三类函数”),这三类函数在教材中占据着较大的篇幅,它融合了方程和数形结合等初中数学的重要思想,沟通了代数、几何之间的联系,是高中函数、三角与解析几何的基础,具有重要的应用价
Function knowledge is the core content of middle school mathematics, and is also an important content of junior high school mathematics. Textbooks are generally arranged in the “number and algebra ” function, including the primary function, quadratic function, inverse proportion function (hereinafter referred to as “three types of function ”) These three kinds of functions occupy a large space in the teaching materials. They integrate the important ideas of junior high school mathematics such as equations and numbers, and communicate the connection between algebra and geometry. They are high school functions, triangles, and analytics. The basis of geometry has an important application price
