I'll do the first one to get you started.
# 1
Recall that the domain is the set of all allowable inputs. So the domain is the set of allowed 'x' values. The range is the set of possible outputs, so it's the set of possible 'y' values.

So the domain and range are...

Domain: {-8, -5, 3, 4, 7}
Range: {-3, 3, 7}

Note: duplicates are tossed out
