Question

What is the set of all possible values that the variable x can take in a relation?

Answer 1

Answer:

A function is a relation (rule) that assigns each element in the domain to exactly one element in the range. The set of all the values which may be input into afunction. That is, the set of all the values the independent variable may assume. Graphically, the domain is the set of all the x-coordinates.

Answer 2

Step-by-step explanation:    

• Relation between two sets is the relationship between elements of two sets which are expressed in an ordered pair (x,y) where the first elements of the pairs are called the domain (x-values) and the second are called the range (y-values).

• For example: In relation R = {(1,2),(3,4),(5,6)} , the set of Domain is {1,3,5} and the set of range is {2,4,6}.

Hence, The set of all possible values that the variable (x) can take in the relation is called the Domain or the Input.
