一元函数是中学阶段数学研究的主要对象和重要内容之一。然而在一些题的求解中,难免会遇到一些简单的二元函数最值问题。考虑到处理问题的客观需要和知识的系统性以及学生进一步认识和理解函数概念,提高认识问题、分析和解决问题的能力,特做如下探索与归纳。
The one-way function is one of the main objects and important contents of mathematics research in middle school. However, in the solution of some questions, it is inevitable that we will encounter some simple binary function value problem. Taking into account the objective needs of processing problems and the systematicness of knowledge and students to further understand and understand the concept of the function, to improve the ability to understand issues, analyze and solve problems, special exploration and induction are as follows.
