Question

The range of a relation is given -2,-1,0,1,2 which domain would make the realation not a function

Answer 1

Any domain that has at least one(1) of the inputs(domain values) having more than one output(range values). For example, a domain of {1, 2, 3} because since there are 5 outputs and only 3 inputs, at least one input would have to pair up with more than 1 output.
