You can put this solution on YOUR website! Is this a function & if it is a function, state the domain and range.
[(1,-2),(-3,-1),(-3,0),(-2,1),(6,3)]
..
This is not a function because for each x input there can be only one y output.
Note that (-3,-1) and (-3,0) have the same x with two different y's
