Respuesta :

I believe the answer is D, since x is only repeating between 0 and 2, yet the y values are changing.

Your answer for this problem, is D.

A function can not have the same repeating lines, on a graph. Meaning as, when you plot your points given on a graph, your dots cant be overlapping, or on the same line.

Attached you can see that none of the dogs are lapping eachother. (First image) 

And that's answer choice D.

But for example, lets take answer choice, A. As ill show you how the dots Do NOT correspond with eachother, making it a function.

As D  (second attachment) They do. 

Final answer; D
