❅☃ 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.
