which of the following of ordered pairs represent a function?

B = (4, 2) (3, -2) (9, 4) (11, -3)

A represents a function because each of the input values {-5, -2, 2, 5} has one and only one output (y-) value associated with it.

The same could be said of B: Each of the four input values {4, 3, 9, 11} has one and only one output (y-) value associated with it.

Thus, in both cases the given relations are also functions.
