For example, we can use lists to describe the domain of functions that are given as sets of ordered pairs. If we are given an equation or graph, we might use inequalities or intervals to describe domain and range.In this section, we will introduce the standard notation used to define ...
Domain and range of a function The domain of a function is all the possible values of x's of ordered pairs; whereas the range of a function is all the possible values of y's of ordered pairs. You can easily find them by graphing the functions or ordered pairs. Let's see how in th...
The domain of a function can also be determined by identifying the input values of a function written as an equation. Interval values represented on a number line can be described using inequality notation, set-builder notation, and interval notation. For many functions, the domain and range can...
How_to_find_domain_and_range_of_functions值域问题 值域问题是高中函数的一个精华问题。有很多问题都是围绕着他展开的。比如说恒成 立问题,值域反求定义与问题(即反函数求定义域)……等等。下面就说一下最基本的集中求 值域问题的类型。 首先要着重说的是:求值域,必先看定义域。所有函数都是如此。 1.单调...

立问题,值域反求定义与问题(即反函数求定义域)……等等。下面就说一下最基本的集中求 值域问题的类型。 首先要着重说的是:求值域,必先看定义域。所有函数都是如此。 1.单调性法 利用函数的单调性。当一个函数单调性很容易判断时,可用定义域来求解。 e.g.1 y=x-√(1-2x).求值域。 解:1-2x≥...
What are the domain and range of a function? What are the domain and range of the graph of a function? In this lesson, learn the definition of domain and range as it applies to functions as well as how it applies to graphs of functions. Moreover, there will be several examples present...
