Question

DOES THIS SET OF ORDERED PAIRS REPRESENT A FUNCTION? {(2,4),(2,5), (2,6), (2,7) }

Answer 1

Answer:
No, this set of ordered pairs does not represent a function.

Explanation:
Functions have one y-value for a given x-value.

Ordered pairs are written (x, y).

In this set, when x=2, it has four y-values (4, 5, 6 and 7), so it cannot be a function.
