Question

Which relation does not represent a function? Question 2 options: A)  { (3, 0)  (0, 3) } B)  { (6, -2)  (5, -2) } C)  { (3, 4)  (3, 5) } D)  { (5, 5) (-5, -5) }

Answer 1

It is C because the first numbers in both coordinates are the same. So if it was on the grid you would see that they would be on the same line.

Answer 2

C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.

Hope that helps.
