函数和图形的相关知识,包括绝对值、负数、关于x轴和y轴的翻折等概念。同时,通过具体例子演示了如何根据特殊点来画出变化后的图像。最后,通过解模和分类讨论的方法,求解了函数的定义域。需要注意的是,对于负数和绝对值,需要先进行相应的变换才能进行翻折。视频内容较为复杂,需要仔细观看和理解。
A function is a correspondence between two sets X and Y that assigns to each element x of set X exactly one element y of set Y. For each element x in X, the corresponding element y in Y is called thevalueof the function at x. The set X is called thedomainof the function, and ...
