This seems to capture your idea of allowing a function to have "multiple domains" (and codomains), though it technically is not the case: by definition a function can have only one domain and one codomain.

- Can a domain have multiple ranges and still be a function?
- Can 1 domain have two ranges?
Is it good to have multiple domains?
If you think having one domain name is sufficient, think again. By not owning multiple domains, you could be costing your business traffic and customers and leaving your brand vulnerable to the competition. One of the most important reasons to purchase more than one domain is to protect against user error.
Can a domain have multiple ranges and still be a function?
Each element of the domain is being traced to one and only element in the range. However, it is okay for two or more values in the domain to share a common value in the range. That is, even though the elements 5 and 10 in the domain share the same value of 2 in the range, this relation is still a function.
Can 1 domain have two ranges?
Can a domain have two ranges? A domain is a set of values that a function can take. A function can only have one domain. However, a function can have multiple ranges.
