❅☃ To find a function you need to look at the x values, if one of the same x value is repeated more then once, it is considered a non function.
❅☃ Option A:
-14
-9
-1
4
6
As you can see no repeated values.
Therefore A is already our function but lets look at the others just in case.
❅☃ Option B
-2
1
9
9
15
9 was repeated therefore it is a non function.
❅☃ Option C
-4
6
6
7
9
6 was again repeated. Non function.
❅☃ And lastly, D.
-16
-11
10
10
16
10 was reapted. Non function.
❅☃ Your answer is A
The answer is going to be v= 4500ft3;S=900ft2
