<span>I cannot say whether Francisco and Ryan started with equivalent expressions but on final simplification they ended up the same. One might reasonably assume they started with equivalent expressions, but who knows if they made any mistakes in their simplifications.</span>
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).
