1.本单元重、难点分析本单元的重点:指数幂的运算性质、对数的运算性质;指数函数、对数函数的概念、图象和性质.本单元的难点:指数函数、对数函数的性质的综合应用.指数函数、对数函数是高考的必考内容,主要考查:定义域、值域、图象及性质的应用.学习本单元知识时,要对如何运用所学的函数知识来研究一个具体函数的方法有较完整的认
1. The unit is heavy and difficult to analyze the focus of this unit: the power of the exponential power, the nature of the operation of the logarithm; the exponential function, the concept, the image and the nature of the logarithm function The difficulties of this unit: exponential function, logarithmic function The comprehensive application of the exponential function, logarithmic function is the compulsory content of the college entrance examination, the main test: the domain, range, image and nature of the application of this unit of knowledge, how to use the function of knowledge To study a specific function of the method has a more complete recognition
