A relation R from set A to set B is, by definition:
AAn element of A
BA subset of A × B
CThe set A × B itself
DA subset of B × A only
Answer & Solution
Correct answer: B. A subset of A × B
A relation from A to B is any subset of A × B. We isolate it by describing a connection between the first and second elements of the ordered pairs.
