Domain is the set of x values given in the set.
Range is the set of y values given in the set.
From the problem, we have :
(6, 6) (-1, 3) (3, 6) and (0, 4)
The x coordinates are 6, -1, 3, and 0
So the domain is {-1, 0, 3, 6}
The y coordinates are 6, 3, 6 and 4
So the range is {3, 6, 4}
You dont need to input duplicate numbers, one is enough.
To summarize :
Domain : {-1, 0, 3, 6}
Range : {3, 4, 6}
