不等式a≥b称为非严格不等式。它具有如下性质(*): “若a≥b,且a≤b,则必有a=b。”在解证题过程中,我们常运用此一性质。如: [例1]:判断函数f(x)=x-4~(1/2)+4-x~(1/2)的奇偶性。(苏州市八七年高考预考试题) 解:由函
The inequality a≥b is called non-strict inequality. It has the following properties (*): “If a≥b, and a≤b, there must be a=b.” We often use this property in the process of solving problems. For example: [Example 1]: The parity of the function f(x)=x-4~(1/2)+4-x~(1/2) is judged. (Suzhou City College Entrance Exam Pre-examination Questions) Explanation: Congyou
