>Function and Map are different concepts that should not be described together
Not in this context. Assuming you are using `map` in the CS sense, B is what is called the "image" of some_function (over the domain A).
In math, a function is a mapping.
Consider the type of `some_function`. In C like notation, it would be `foo some_function(goo x)`. Which indicates that some_function takes an arguement of type `goo` and returns a value of type `foo`. In other words, some_function maps Goo to Foo (where Goo and Foo represent the set of all values of type goo and foo).
