Exercise · ZW-BINARY-RELATION-004 · ★☆☆ Basic
If \(R=\{(1,2),(2,3)\}\), what is the range of \(R\)?
Choose one option.
Show answer
- B. \(\{2,3\}\)
Explanation
The range is the set of second components of the pairs: 2 and 3.
Review the concept: Binary relation
A set of ordered pairs \((a,b)\) specifying which elements of \(A\) are related to which elements of \(B\).
\[R \subseteq A \times B\]
