Question

Which set represents the range of the function shown? {(−1, 5), (2, 8), (5, 3), (13, −4)}

A {−1, 2, 5, 13}
B {−4, 3, 5, 8}
C {(5, −1), (8, 2), (3, 5), (−4, 13)}
D {−4, −1, 2, 3, 5, 5, 8, 13}

Answer 1

B) {-4, 3, 5,8} because the set of all second components of the ordered pairs of a relation R is known as the range of a relation.
