b-(-2,-1)

Step-by-step explanation:

Answer 2

Answer:

b - (-2,-1)

Step-by-step explanation:

A function is a mapping in which each element of the domain, or input, is mapped to one element of the range, or output.

In this mapping, the input value -2 is mapped to both 2 and -1; this makes the points (-2, 2) and (-2, -1).  If one of these two was removed, the mapping becomes a function.

The only one of these listed in the values given is (-2, -1).
