What is another name for a relation that has each element in its domain paired with exactly one element in its range?

Step-by-step explanation:

A function is a relation in which each element of the  domain is paired with exactly one element of the  range.

A relation is a set of ordered pairs. The set of the first components of each ordered pair is called the domain and the set of the second components of each ordered pair is called the range. Consider the following set of ordered pairs. The first numbers in each pair are the first five natural numbers. The second number in each pair is twice that of the first.

{(1,2),(2,4),(3,6),(4,8),(5,10)}

The domain is{1,2,3,4,5} and the range is{2,4,6,8,10}

So, this relation is a function.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
