B is the only table which contains a function. Each value of x in a function must have a unique value. Since A has more than one answer for 4, C has more than one answer for 2, and D has more than one answer for 1, none of these can be functions.

Hi!

So when you havea function, the x values can not be repeated otherwise it is not a function.

In A 4 is repeated so that's wrong

B, nothing is repeated so that's right

C, 2 is repeated o it is wrong

D, 1 is repeated so it is wrong


B is your answer!

Hope this helps!
