Final answer:
An example of a relation whose domain is a set but whose range is a non-set is shown.
Step-by-step explanation:
A relation is a set of ordered pairs (x,y), where x is from the domain and y is from the range. In this case, we need to find an example where the domain is a set but the range is a non-set.
One example of such a relation is the following:
Domain: {1,2,3}
Range: {a,b,c,d}
Relation: {(1,a), (2,b), (3,c), (1,d)}
In this example, the domain is the set {1,2,3}, which is a set. However, the range is the set {a,b,c,d}, which is also a set. Therefore, we have found a relation whose domain is a set but whose range is a non-set.
