| 摘 要： | 关于函数的值域(最值)的求解方法,是中学数学教学中的一个难点,也是一个重点.在现行中学教材中没有专门安排的有关内容作出介绍,但在中学数学教学以及各种考试中,却处处可遇到求函数值域(最值)的问题.因此,我们有必要对函数的值域(最值)的求解方法作出归纳.就是对函数的值域(最值)的求解方法作出归纳.

| Abstract: | The methods of solving functions range is a difficult also an important issue of high school mathematics. These are not any specific arrangements for the presentation of the contents in the existing secondary school textbooks. But in the high school mathematics and all kinds of examination, you will meet problems in functions range everywhere. Therefore, it is necessary for us to sum up the solvingmethod to the functions range. This paper sums up the solving method to the functions range. |
