函数是高中数学主要内容,涉及函数的应用问题,题源丰富、背景深刻、题型新颖、解法灵活,是历年高考的热点之一.有很多应用题涉及到“方案最优化”问题,其解决方法一般是建立“目标函数”,从而化归为求目标函数的最大值或最小值问题. Function is the main content of high school mathematics, involving the application of functions, rich sources of questions, deep background, novel types of questions, and flexible solution methods. It is one of the hot spots in college entrance examinations over the years. There are many applications related to the “program optimization” problem, which solves The method is generally to establish the “objective function”, so that the problem of finding the maximum or minimum value of the objective function.
