1专题综述函数贯穿高中数学教学的始终,是高中数学的核心知识和主干知识,也是高考中极为重要的内容和素材。以函数为主体的试题在历年的高考试卷中占有较大的比重,在选择题、填空题、解答题中都有体现。一般说来,选择题、填空题主要以基本初等函数为载体,考查函数的概念、定义域、值域、单调性、奇偶性、对称性、周期性以及函数图像、导数的几何意义等,关注函数知识的应用以及函数思想方法的渗透,着力体 1 Thematic overview The function runs through high school mathematics teaching, is the core knowledge and backbone of high school mathematics knowledge, but also the college entrance examination is extremely important content and material. The questions with the function as the main body occupy a larger proportion in the college entrance examination papers over the years, which are reflected in the multiple choice questions, the blank questions and the answers to the questions. In general, multiple-choice questions and blank-fill questions mainly focus on basic elementary functions as vectors and examine the concept, domain, range, monotonicity, parity, symmetry, periodicity, geometric meanings of functions and derivatives of functions, The application of function knowledge and the infiltration of function and method of thinking,
