What's a Codomain in Maths?

The codomain of a function is the set of its possible outputs. ... In other words, the codomain of f is the set of real numbers R (and its set of possible inputs or domain is also the set of real numbers R).

What is codomain in maths with example?

The Codomain is the set of values that could possibly come out. The Codomain is actually part of the definition of the function. And The Range is the set of values that actually do come out. Example: we can define a function f(x)=2x with a domain and codomain of integers (because we say so).

Is codomain the same as range?

The difference between codomain and range is a bit difficult to find out, because both the terms sometimes means the same. ... The codomain is the set of all possible values which can come out as a result but the range is the set of values which actually comes out. Also, learn relation of domain and range here.
