一、内容和内容解析本节课选自《普通高中课程标准实验教科书数学1必修本(A版)》的第三章的3.2.1几类不同增长的函数模型的第二课时.函数的增长快慢问题是函数重要的性质之一,它揭示了客观世界中量的相互依存又相互制约的关系.它与函数的单调性有相似的地方,但不一样,掌握函数的增长性对于理解函数性质特别是对于解决函数类应用问题有较大的帮助,这也为今后学习其它函数 First, the content and content analysis This class is selected from 3.2.1 of the third chapter of “General high school curriculum standard experimental textbook mathematics 1 compulsory version (A)” of the second growth of the function model of different types of growth. The issue of speed and slowness is one of the important properties of a function, which reveals the amount of interdependence and mutual restraint in the objective world. It has similarities to the monotonicity of functions, but not the same. Grasping the growth of functions is essential for understanding the nature of functions Especially for solving the application of the function class has a greater help, which also learn other functions for the future
