A constant function is a special case of which type?
Correct Answer
Many-one function
Explanation
In a constant function, every domain element maps to the same single element in the codomain — in the extreme case, all of \(a, b, c, d\) map to \(k\). This is a special (extreme) case of a many-one function: the codomain element \(k\) is the image of all domain elements. The other codomain elements \(m, n\) are never reached.
