所谓ｍａｘ[ｆ(ｘ) ,ｇ(ｘ) ]或ｍｉｎ[ｆ(ｘ) ,ｇ(ｘ) ]型函数 ,是指在ｆ(ｘ)、ｇ(ｘ)的公共定义域的不同部分 ,取这两个 (或两个以上 )函数值最大的函数式 (或最小的函数式 )作解析式的函数 ,解这类函数有关的问题的最佳方法是数形结合 .本文例举几例说明求解策略 .例 1 已?
The so-called max[f(x), g(x)] or min[f(x), g(x)] functions refer to different parts of the common domain of f(x) and g(x). The two (or more) functional formulas (or the smallest functional formulas) with the largest function values are used as analytical functions, and the best way to solve the problems associated with these types of functions is the combination of number and shape. Solving strategy. Example 1 Has?
