In ordered pair , the x coordinate shows the input value and the y-coordinate shows the output value.

In the given lists only list B is representing  a function since each input corresponds to a unique output.

In list A. , 2 corresponds to two different values i.e. 5 and 1 .

Thus its not a function.

In list C., 2 corresponds to two different values i.e. 5 and 3 .

Thus its not a function.

In list D. 4 corresponds to two different values i.e. 0 and 3 .

Thus its not a function.
