函数是初、高中数学的重要内容与衔接点,是描述现实世界变量之间关系的重要数学模型,函数图象能直观地反映函数的变化关系与规律,解读函数的图象十分有利于数形结合思想、运动变化思想的树立,对于分析判断、综合运用知识、抽象思维能力的提高有着重大的意义,也将为高中数学学习做准备.
Function is the important content and cohesion point of the mathematics of early and senior high schools. It is an important mathematical model that describes the relationship between real world variables. The function image can intuitively reflect the changing relations and laws of the function, and the image of the interpretation function is very favorable to the number shape. The combination of thinking and movement change ideas has great significance for the analysis and judgment, the comprehensive application of knowledge, and the improvement of abstract thinking ability. It will also prepare for the study of high school mathematics.
