## thatjacksonguy 2 years ago are the ordered pairs(-2,-1),(-1,0)(6,3) and (-2,-1) a function?

1. thatjacksonguy

what is the domain and range

2. Mertsj

A function is a set of ordered pairs in which no two ordered pairs have the same first number. So is it a function?

3. thatjacksonguy

no

4. Mertsj

Good job. The domain is the set of x values and the range is the set of y values.

5. thatjacksonguy

help me understand that im a little confused on that part

6. Mertsj

Do you know which is the x value of an ordered pair and which is the y value?

7. thatjacksonguy

yea the first number in the pair is x second is y

8. Mertsj

So what are the x values of your ordered pairs?

9. thatjacksonguy

-2,-1,6,-2

10. Mertsj

So put them in order (don't list any number twice), put braces around them and that's your domain.....the set of x values. Do the same with the y values and that will be the range.

11. thatjacksonguy

so i dont put -2 twice??

12. Mertsj

Did you see where I typed not to list any number twice?

13. thatjacksonguy

lol yea just wanted to be sure this is very important to my grade right now

14. Mertsj

{-2,-1,6} That's the domain.

15. thatjacksonguy

thanks a bunch you rock

16. Mertsj

yw. Don't forget to do the range.

17. thatjacksonguy

will do
