Question

Which graph represents a relation that is not a function?

Answer 1

I think C

Answer 2

C use the vertical line test. Use a pencil and go left and right if two point touch the pencil at the same time then they are not functions

One x can not have 2 different y

Answer 3

Okay, so it's A that's not the function.

Answer 4

No, u were right its C

Answer 5

Huh...?
Oh, I get it now! X is the same, but y has two different points! Thanks!

Answer 6

Yes. If u don't really get it, try putting a pencil on the graph vertically. U should see that it will intersect the pencil twice. This means it's not a function
