Question

What change is needed to make this relation a function?
{(1, 2), (2, 5), (3, 8), (3, 9)}

A. Change the 8 to a 5.

B. Change one of the 3's to a number not yet used.

C. Change both 2's to 6's.

D. No changes are needed.

Answer 1

change one of the 3's to a number not yet used.

The reason I say this, is because a function cannot have two x-values that are the same. They can have 2 y-values that are the same, just not the x-values.
