what are u trying to find exzactly??? are u trying to find the domain numbers??

anonymous · Answer

list the first numbers in each ordered pair

anonymous · Answer

if its on a table then the domain is all straight down the  left sideand range is down right side

debbieg · Answer

OK, but the important thing is: 

The DOMAIN is the set of all the 1st coordinates of each ordered pair in a relation (which is just a set of ordered pairs).

The RANGE is the set of all the 2nd coordinates of each ordered pair in a relation.

It doesn't matter if you are given the relation as ordered pairs, in a "table" listing x's and y's, as an equation, as a graph... etc.

soooooooo a ?

debbieg · Answer

Yes, a. :) I should have added, in stating the domain "set", you don't need to "double-list" items that appear in two different ordered pairs. :)
