本文从最值问题与函数值域的联系,最值问题与不等式的联系两个方面,也来谈研究最值问题的解题思路与方法.(一)最值问题与函数值域的联系函数的最值问题,往往与函数的值域有密切的联系.事实上,如果函数y=f(x)的最大值为b,最小值为a,那么函数y=f(x)的值域必定是数集[a,
In this paper, we discuss the ways and means of solving the most significant problems from the connection between the most value problem and the functional value range, the connection between the most value problem and the inequality. (1) The connection function between the most value problem and the functional value range In fact, if the maximum value of function y = f (x) is b and the minimum value is a, then the range of function y = f (x) must be bound to Is a few sets [a,
