Answer:
The domain of the relation is [tex][(5,16,18,21][/tex]
Step-by-step explanation:
we have
[tex][(15,65),(21,70),(18,73),(16,62)][/tex]
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
[tex][(5,21,18,16][/tex]
order them from lowest to highest -------> [tex][(5,16,18,21][/tex]
The range is
[tex][65,70,73,62][/tex]
order them from lowest to highest ------->[tex][62,65,70,73][/tex]
