一、内容和内容解析内容:函数是描述客观世界变化规律的基本数学模型,不同的变化规律需要用不同的函数模型来描述。本节的教学目标是认识指数函数,对数函数等函数模型的增长差异,体会直线上升、指数爆炸、对数增长等不同函数类型增长的差异;将实际问题转化为函数模型。 I. Content and Content Analysis Contents: Function is the basic mathematical model describing the law of change in the objective world. Different rules of change need to be described by different function models. The objective of this lesson is to recognize the differences in the growth of exponential functions, logarithmic functions, and other functional models, to understand the differences in the growth of different function types such as straight-line rise, exponential explosion, logarithmic growth, etc. The actual problem is transformed into a functional model.
