Answer:
yes it is
for a relation to occur,
1. the domain must have unique images in the codomain
2. the whole domain must be mapped
when we look at the function above, we have
2________-4
6________-2
4________-2
5________-4
-8_______-6
Step-by-step explanation:
we see that all the domains are mapped uniquely to codomains
hence, it is a function, having a domain and range
