Identify the domain and range of the relation.
{(-9, 2), (-4, 2), (3, 2), (9, 2)}

Domain is the x values. So based off of that...
D= {-9,-4,3,9}
The range is the y values. So based off of that...
R= {2,2,2,2}
If your teacher says not to repeat then this is your answer below...
D= {-9,-4,3,9}
R= {2}
Hope This Helps!

Ithink the answer is c just trying to others
