二次函数在给定区间上的最值宁夏陶乐县一中张占兵讨论函数的值域，得到函数值的变化范围，是研究函数性质的一个重要方面．而求函数在定义域上的最大值和最小值，又是求得函数值域的主要手段之一．二次函数ｆ（ｘ）＝ａ（ｘ＋ｍ）２＋ｎ的极值问题，在初中《代数》中是难...
The maximum value of the quadratic function in a given interval The Zhang Zhanbing in the first county of Taole County, Ningxia, discusses the range of the function and obtains the range of the value of the function. This is an important aspect of studying the nature of the function. Finding the maximum and minimum values of the function in the defined domain is one of the main means for obtaining the function range. The extreme problem of quadratic function f(x)=a(x+m)2+n is difficult in junior algebra algebra...
