What is the difference between range and codomain?

Understand the Problem

The question is asking for the distinction between range and codomain in mathematical terms. The range refers to the set of actual output values of a function, while the codomain is the set of values that could potentially be outputs, as defined by the function itself.

Answer

The codomain is the set of all possible values which can come out as a result, but the range is the set of values that actually comes out.

The codomain is the set of all possible values which can come out as a result, but the range is the set of values that actually comes out.

Answer for screen readers

The codomain is the set of all possible values which can come out as a result, but the range is the set of values that actually comes out.

More Information

This distinction is important in understanding how functions map inputs to outputs in mathematics.

Tips

Students often confuse codomain and range because they are both related to function outputs. Remember that the range is always a subset (or equal) to the codomain.
