Question

Determine if the set of ordered pairs represents a function. Explain why or why not. (2 points)

{(-4, 4), (-2, 2), (0, 0), (-3, -2)}

Answer 1

In order for a set of ordered pairs to be a function there can not be more than one x-value with a different y-value.

In this case, the set of ordered pairs: (-4, 4), (-2, 2), (0, 0), (-3, -2) is a function! There are no repeated x-values.

Hope this helped!
