Exercise · ZW-FUNCTION-003 · ★☆☆ Basic
A relation assigns the same element of \(A\) two different values in \(B\). What is it?
Choose one option.
Show answer
- B. Is not a function
Explanation
If a relation sends one element to two different values, uniqueness of the image fails and so it is not a function.
Review the concept: Function
A function f from A to B assigns to each element of A exactly one element of B. A is the domain and B the codomain.
\[f:A\to B\]
