Question

For a relation \(R\), the range is the set of all:

Options

• elements of the domain not used by \(R\)

• first components of all ordered pairs in \(R\)

• second components of all ordered pairs in \(R\)

• elements of the Cartesian product not in \(R\)

Answer 1

The range is the actual set of output values obtained in the relation. These are precisely the second components of its ordered pairs.
