函数的应用问题属于实际问题,带有很强的现实生活色彩,数量关系、信息存储方式、情景设置、语言表达形式等都不同于常规训练中的简单问题.将题中所有包含数量关系的文字语言、图像语言抽象概括为符号语言(数、式、函数、方程、不等式),建立恰当的数学模型是解题的难点和关键.本文探讨如何建立拟合效果最好的函数模型.例1一天,百万富翁杰米碰到了一件奇怪的事,
The application of the function is a practical problem, with a strong real life color, the number of relations, information storage, situation setting, language expression, etc. are different from the simple problems in the routine training. Language and image language are abstractly summarized as symbolic languages (numbers, formulas, functions, equations, inequalities). Establishing an appropriate mathematical model is the difficult and key point for problem solving. This article discusses how to create a function model with the best fitting effect.
