You need to participate.

Answer 6

(x-value, y-value)

Answer 7

Okay A B C D

Answer 8

First number in the parenthesis is an x-value.

Answer 9

It is a function if the x elements don't repeat twice for the y elements, but the y's can repeat. Meaning (2,3) (3,5) see (x,y) x's can't repeat.

Answer 10

What's fascinating is, 1 is unique though, but you won't have to consider that :P

Answer 11

so what is it iam confused

Answer 12

Tell me the x-values in the first option.

Answer 13

Just to make sense of it, lets look at your D) (3, 4), (-1, 6), (3, 3), (-6, 2)
you see your values (x,y) in all of them right? As I said the x's cannot repeat. You can see the 3's repeated twice, (3,4) and (3,3) meaning it's NOT a function.

Answer 14

This is a function, you can't have more than one x values but you can for y values
