y 1 5 -2 7 0
c.

In B, -3 is an x-value that is used twice.

In C, -1 is shown as being mapped to 10 and 18 (more than one value).

In D, the graph shows -4 produces 2 different output values.

The appropriate choice is the set of ordered pairs shown in A.

A. {(8,0), (0,8), (1,-6), (4,-7), (-1,8)}
