函数与导数是中学数学的基础,是学习其他知识的关键。函数是每年高考必考的内容,主要考查函数的定义、图像与性质,利用函数解决实际问题。导数是研究函数的工具,利用导数可以更好地研究函数,解决实际问题。高考试题对函数与导数的考查往往与其他知识相结合,综合考查考生分析问题与解决问题的能力。一、明确要求,找准目标搞清函数的概念,会求一些简单函数的定义域和值域,理解函数的图像与性质,掌握 Functions and derivatives are the basis of secondary mathematics and are the key to learning other knowledge. Function is the annual college entrance examination will be the content of the main test function definition, image and nature, the use of functions to solve practical problems. Derivatives are tools for studying functions. Derivatives make it possible to better study functions and solve practical problems. Examination of the entrance examination of the function and derivative of the often combined with other knowledge, a comprehensive examination of candidates to analyze the problem and the ability to solve the problem. First, a clear request, identify the target Identify the concept of the function, will seek some simple function of the domain and range, understand the function of the image and nature of master
