Question

What is the domain of the relation?

Answer 1

Answer:

The domain of the relation is $[(5,16,18,21]$

Step-by-step explanation:

we have

$[(15,65),(21,70),(18,73),(16,62)]$

Remember that

The domain of the relation are the values of x

The range of the relation are the values of y

therefore

The domain is

$[(5,21,18,16]$

order them from lowest to highest ------->  $[(5,16,18,21]$

The range is

$[65,70,73,62]$

order them from lowest to highest ------->$[62,65,70,73]$
