Answer:

The answer is the third table

Explanation:

Looking at the first table, that is a many-to-one function. We can say it's many-to-one because when looking at the inputs (x), for both 8 and 11, the output is the same. Remember, In a function, x can have only one output. Therefore, this satisfies that requirement, but it is not a one-to-one function.

In the second table, we have one-to-many. When looking at the inputs (x), there are the numbers 2, 8, and 8. Since the number 8 repeats and has different outputs 7 and 15, this makes it a one-to-many. Additionally, it is not a function, because it should not have two different outputs.

The third table is a one-to-one function. This is because the inputs 2,8 and 11 each have one output. Hence, it is also a function, and this is the correct answer.
