Answer 1

C. No, because one x-value corresponds to two different y-values.

Explanation:

Every relation or table of values that represents a function must have exactly one range value (output) assigned or related to one domain value (input). That is to say, each x-value must not have more than one y-value assigned to it.

From the table of values given, an x-value, 8, has more than one y-value, 5 and 8, assigned to it.

Therefore, it is not a function.

The answer is:

C. No, because one x-value corresponds to two different y-values.
