Answer:
Options a,b and c preserves the function
Step-by-step explanation:
Assuming the missing table is the one shown in the attachment
we know that
A function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output
In this problem
If the point (-6,-5) is added, the function is not preserved, because for one input it will have two outputs
so
For x=-6
y=9 and y=-5
If the other points are added the function is preserved, because for one input it will have one output
therefore
Options a,b and c preserves the function
