Question

PLEASE HELP ME

Answer 1

Functions can only have 1 value of 'x'

Answer 2

Only one input(x)

Answer 3

So which one do you think?

Answer 4

Y? @iGreen.

Answer 5

No, 'y' has two 9's in it, don't you see the two arrows coming from '9'?

Answer 6

That means there are two of them..so Y is incorrect.

Answer 7

no W

Answer 8

No, that's incorrect also.

Look at the numbers on the left for each of the four options..

You can only have 1 arrow coming out of each of them.

W has two arrows coming from '3' so it is not a function.

Answer 9

X it has to be

Answer 10

No, X has two arrows coming out of '5'..

Answer 11

oh ok thanks
