一. 理解函数(function),定义域(domain),值域(range)的含义,并学会根据图像判定是否是函数,以及对函数进行分类 函数的类型 这两种不是函数 函数是一种关系式,一个输入只能对应一个输出,上图中的(c)和(d)一个横坐标对应两个y值的都不是函数。 二. 学会求函数的值域或复合函数(composite function)的值域 对于...
Learn what the domain and range mean, and how to determine the domain and range of a given function. The domain of a function is the set of all possible input values, while the range is the set of all possible output values.

More About the Domain and Range As a way of a summary, let us recap a few things. First the domain is where a function is well defined, and the range is the set of points that are reached through the function. In terms of the calculations required, it is typically easier to find th...

y=8y=8 is a straight line perpendicular to the yy-axis, which means that the range is a set of one value {y|y=8}{y|y=8}. Set-Builder Notation: {y|y=8}{y|y=8}Step 3 Determine the domain and range. Domain: (−∞,∞),{x|x∈R}(-∞,∞),{x|x∈ℝ} Range: {y|y...
点f(a)被称为a的像(image),并且集合A(一个定义域的子集)的像,是包含A中所有点的像的目标的子集。整个定义域的像称为函数的值域(range)。(注意值域与目标的区别,并且值域是目标的一个子集,有的地方把目标叫上域codomain) 2.1.1 逆映射(Inverse Mappings) ...

The domain is all the x-values, and the range is all the y-values. To give the domain and the range, I just list the values without duplication: domain: {2, 3, 4, 6} range: {−3, −1, 3, 6} (It is customary to list these values in numerical order, but it is not ...
