最值问题的重点内容是函数的最值问题。有些最值问题直接以求函数的最值的形式出现;有些最值问题(例如从生活实际中经过初步的数学加工形成的问题)虽然不是直接以求函数的最值问题面目出现,但经过适当的转化能够变成函数的最值问题。当然也有例外,有些最值问题(特别是在选择题、填空题出现的问题)可以用数形结合法解决,而无需转化为函数的最值问题,转化成函数的最值问题可能更繁琐。因此解最值问题有两条
The most important issue of the value problem is the function’s maximum value. Some of the problems of the most value are directly in the form of seeking the most value of the function; some problems of the most value (such as the problems formed by the preliminary mathematical processing from the reality of life), although not directly appearing in order to find the value of the function, but after appropriate The conversion can become the problem of the maximum value of the function. There are exceptions of course, some of the most value problems (especially in the multiple-choice questions, fill in the blank questions appear) can be solved using the number and shape combination method, and do not need to be converted to the function of the value of the problem, the conversion into the function of the value of the problem may be more tedious. So there are two problems with the solution
