Evaluate the following relation. { (14, 12), (15, -2), (12, -5), (-2, 15) } The relation is a function

A. true

B. false

It is true because each input has only 1 output.

in other words, each x value has a separate y value. An x value doesn't come twice and have a different y value each time. If it did, it wouldn't be a function.

I think the answer is A. True
