Question

What are the domain and the range of the relation?

{(−9, 7), (−4, 3), (−1, −6), (2, −8), (5, 12), (10, 11)}

Choose exactly two answers that are correct.

A.
domain: {−8, −6, 3, 7, 11, 12}

B.
domain: {−9, −4, −1, 2, 5, 10}

C.
range: {−9, −4, −1, 2, 5, 10}

D.
range: {−8, −6, 3, 7, 11, 12}

Answer 1

Do you think you know it

Answer 2

To find the domain of a list of ordered pairs, you can group together the first element of each ordered pair, and put them in a set.
The same can be repeated for the range, but use the second element of the ordered pairs instead.

Answer 3

Example: Given relation {(1,2),(4,6), (7,9)}
domain: {1,4,7}, range {2,6,9}
