Which of the following relations is a function?
• {(1.-6). (3. - 5), (1,0)
O None of the other answers are correct
Of(0,5), (5, -1). (5,9)
o {(6,1), (6,2), (6,3)}
o {(0,8), (1,7) (2,6)}
Only the last one is a function. This is because there are no repeating x values, which are the first numbers. It is okay for there to be repeating y values, but not x.
