函数和图形 函数和图形的知识,重点讲解了反函数的概念和求解方法,以及原函数和反函数的图像交点问题。同时,视频还介绍了如何画出整体函数和部分函数的图像,以及绝对值函数的图像特点。在讲解过程中,视频提到了一些做题的方法和技巧,帮助学生更好地掌握知识。最后,视频还解答了一些学生在做题过程中遇到的问题,并提供了...
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。
Letfandgbe two functions such that f(g(x))=xfor everyxin the domain ofg and g(f(x))=xfor everyxin the domain off. The function g is the inverse of the functionf, and is denoted byf−1(f-inverse). Thus,f(f−1(x))=xandf−1(f(x))=x. The domain offis equal to th...

The need for improved mathematics education at the high school and college levels has never been more apparent than in the 1990's. As early as the 1960's, I.M. Gelfand and his colleagues in the USSR thought hard about this same question and developed a style for presenting basic mathematic...
7.2 Functions and Graphs Objective: Understand functions. Fill out input-output tables. Determine if relations are functions. What is a function? We will use a machine as an example of a function. Eli Whitney is famous for what invention? The Cotton Gin!!
