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.

What is the relation between range and codomain?

The Codomain and Range are both on the output side, but are subtly different. 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.

Is codomain subset of domain?

In short terms, we can say that range is the subset of the codomain. It is not important that a function might satisfy all the values of the codomain. However, the values that we get after entering domain values in a function are the range. Thus, it is part of the codomain set.
