You can put this solution on YOUR website! a) Determine if the relation is also a function
Not a function as some x-values have more than one y-value.
b) Give the domain or range of the relation or function
Domain:: {7,8,3}
Range:: {6,1,9,2,7}
{ (7,6), (8,1), (3,9), (8,2), (7,7), (3,2) }

Rule:
A function can have two of the same  values, but it cannot have two identical  values.
{ (7,6), (8,1), (3,9), (8,2), (7,7), (3,2) }
IS NOT A FUNCTION because the ordered pairs (8,2) and (3,2) have the same coordinate
The domain is just all the values and the range is just all the values.
domain: { 3,7,8}
range:{1,2,6,7,9}
