1本单元知识网络2重点、难点、热点分析指数函数、对数函数(以下简称两类函数)是基本初等函数中的两种重要函数,研究它们既有拓展基础知识的意义,又有深化函数学习的意义.本单元的重点是两类函数的图象、性质及其应用.要求能结合它们的图象,说明它们的性质,并利用这些性质比较 1 unit of knowledge network 2 key, difficult, hot analysis of exponential function, logarithm function (hereinafter referred to as two types of functions) are two basic functions of the two important functions, they both explore the significance of basic knowledge, but also deepen the function The significance of learning The focus of this module is the image, nature and application of the two types of functions, which require that their properties be combined with their images and used to compare these properties
