Relations and functions have many applications in the real world. A relation is any set of ordered pairs. The set of all first coordinates is called the domain of the relation, and the set of all second coordinates is said to be the range of the relation. There are two ways to specify...
像(image):經函數順向處理的結果,相當於應變數。 定義域(domain):自變數的集合。 對應域(codomain):應變數存在的集合,為值域的超集,當中不屬於值域的元素無法在定義域中找到可對應的自變數。 值域(range):應變數的集合,為對應域的子集。 上面的敘述有些饒口,改用圖示理解會容易許多: f(x) 函數將 X 集合...
Each element in the domain, each daughter, can only have 1 mother (element in the range). Some people find it helpful to think of the domain and range as people in romantic relationships. If each number in the domain is a person and each number in the range is a different person, the...
Relations and Functions Section 2-1 Relations and Functions Objective: To graph a relation, state its domain and range, and determine if it is a function. To find values of functions for given elements of the domain. Algebra II Relation, Domain, Range Relation – A set of ordered pairs. D...
Relations and Functions Suppose we have the relation { (5,6) , (-3,0) , (1,1) , (-3,6) } 5 -3 1 1 6 NOT A FUNCTION Domain Range Domain and Range The set of all inputs, or x-values of a function. It is all the x – values that are allowed to be used. Range The ...
A function associates each element in its domain with one and only one element in its range. Example: Determine whether the following are functions a) A = {(1, 2), (2, 3), (3, 4), (4, 5)} b) B = {(1, 3), (0, 3), (2, 1), (4, 2)} ...

What are the domain and range of a relation? The set of all the starting values in a relation is called the domain and the set of all the ending values is called the range. The domain is what you start with; the range is what you end up with; the domain is thex's, the range ...
Studying functions is the first step in developing analytics skills for mathematical modeling. In this module, we develop the concept of a function and review important algebraic operations on functions used later in this course. We will also study the important features, like domain, range, and ...
