Question

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

Change the 8 to a 5.

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

Change both 2's to 6's.

No changes are needed.

Answer 1

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

Answer 2

please no direct answers

Answer 3

The rule is that a function cannot map two different "range" values to the same domain value. So the last two ordered pairs make it NOT a function. I'd say "B" is a viable approach. The algorithm here seems to be y = 2n + 1, so changing the second "3" to a 4 would keep the function viable
