函数是高中数学的重难点学习内容之一,是高考命题的热点问题,因此学好函数部分的知识对于同学们学好数学具有非常重要的意义。但是由于函数知识本身的复杂性和抽象性,很多同学在解函数题时感到困难重重,现就函数的解题方法及同学们在解题过程中存在的问题,举例分析。一、利用函数的单调性和奇偶性解题函数作为一种数学思想,是联系数与形 Function is one of the most difficult and difficult points of high school mathematics learning content, which is a hot issue in college entrance examination proposition. Therefore, knowledge of the function part is very important for students to learn mathematics well. However, due to the complexity and abstraction of the function knowledge itself, many students find it difficult to solve the problem. Now we give an example analysis of the method of solving the problem and the problems students have in solving the problem. First, the use of monotonicity and parity function Solving the problem as a mathematical idea is the number and shape
