Question

What are the domain and the range of the relation?


{(−4, 3), (0, −10), (6, −6), (7, 0), (9, −5), (13, −2)}



Choose exactly two answers that are correct.









A.

domain: {−10, −6, −5, −2, 0, 3}








B.

domain: {−4, 0, 6, 7, 9, 13}








C.

range: {−10, −6, −5, −2, 0, 3}








D.

range: {−4, 0, 6, 7, 9, 13}

Answer 1

say the relation is {(x,y)}
the domain is {x}
the range is {y}

Answer 2

domain just list all the x values (the first number of every pair)
range just list all the y values (the second number of every pair)

Answer 3

For example if we have the relation {(5,2),(5,3),(6,4),(7,10)}
the domain is {5,6,7}
the range is {2,3,4,10}

Answer 4

so look at your relation
can you just list the first number of every pair?
