Question

Given: {(5, 2), (7, 4), (9, 10), (x, 5)}, which of the following values substituted for x will make this relation a function?

Answer 1

Step-by-step explanation:

It's a function if there are not two different y values for the same x value.

So any value of x except 5, 7, and 9 will make the relation a function.
