which of the following represents the range of the relation {(9,5),(-3,8),(9,-10)}?

1 answer

The range of a relation is the set of all the second elements (y-values) in the ordered pairs. In the relation \({(9,5), (-3,8), (9,-10)}\), the second elements are:

  • 5 (from the pair (9, 5))
  • 8 (from the pair (-3, 8))
  • -10 (from the pair (9, -10))

Thus, the range of the relation is \({5, 8, -10}\).
