Question 626193: (2,1)(22,-5),(37,1),(2,7),(56,7) what is the domain
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! The domain is the set of possible x inputs.
In this case, the set of x values here is {2,22,37,2,56} which sort to {2,2,22,37,56}
Toss out any duplicates to get {2,22,37,56}
So the domain is {2,22,37,56}
