Question

Which of the following best describes the ordered pairs listed below?

(-2, -4), (0, -6), (-2, -11), (7, -13)


A. neither a relation nor a function


B. function only


C. both a relation and a function


D. relation only

Answer 1

D. Relation only.

Explanation:

This is a one-to-many relation ( because -2 maps on to -4 and -11) so it is a relation but NOT a function. A function is a one-one or many-to-one relation.
