Which represents a function ?

Second option

Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

For the first table, this would not represent a function.

Notice that the -3 and the -3 correspond to different y-coordinates. In order for a relation to be a function, each x-coordinate must pair with one y-coordinate.

The second relation would be a function because notice that each x-term appears only once with a unique y-term so your answer would be the second one.

For the third table, the 0 gets paired up with two different y-values.

For the last relation, the x-term, -12, gets paired up with 4 and 24 which means that the relation can't be a function.
