A relation is a mapping or pairing of input values with output values.

A mapping. It need not be a function.
That's a proper function, a conformal mapping, etc.

This is true. If a given input value yields four output values that relationship can be best described as a relation.

A one-to-one function, a.k.a. an injective function.
A function, f, is usually a mapping from a set of input values. This set, whose elements are often denoted by x, is called the domain.A function, f, is usually a mapping from a set of input values.

It is simply a mapping. It could be a function but there are several conditions that need to be met before the mapping can become a function and there is no basis for assuming that those conditions are met.

something
The domain is the set of values of the input while the range is the set of output values.
No. If an input in a function had more than one output, that would be a mapping, but not a function.
It is a relationship from one set to another, which is not a function.
