Reasoning: A function consists of the pairs (2, 3), (x, 4), and (5, 6). What values, if any, may x not assume?

For the relation to be a function, x may not assume 2 or 5.

For the relation to be a function, x may not assume 2, 3, 4, 5, or 6.

x may assume any real number and the relation will still represent a function.

For the relation to be a function, x may not assume 3, 4, or 5.
