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

The domain is a set containing all the x-coordinates.
The range is a set containing all the y-coordinates.
If the same x-coordinate or y-coordinate appears more than once, list it only once in the domain and range sets.

Answer 2

@mathstudent55 How do I check for the x & y coordinates?

Answer 3

In each ordered pair, the first number is the x-coordinate, and the second number is the y-coordinate.
