      (Show Source): 
You can put this solution on YOUR website! The domain is the set of allowable inputs or x values. 
 The range is the set of possible outputs or y values.
 
 So the domain is the set {-9, -5, 1, 3, 7}
 
 and the range is the set {4}
 
 Note: Remember to sort and get rid of any duplicates. Sorting isn't 100% necessary, but it's nice to keep everything consistent.
