Answer:

top left

Explanation:

To be a function, each value of x has to be different.

In the top left table, all values of x are different.

This is a function.

Top right has -2 for x twice: not a function.

Bottom left has -5 for x more than twice: not a function.

Bottom right has 30 for x twice: not a table.
