Answer:
Range
Step-by-step explanation:
The range of a graph tells you <u>all of the possible y-values</u> for it.
There is also the domain, which tells you all of the possible x-values.
For example, if you have this relation, that only has these points:
(1, 2) (2, 4) (3, 6)
Then the range is {2, 4, 6}. This means the "y" can ONLY be the numbers stated here.
The domain would be {1, 2, 3}.
