First, look at the formula... what number wouldn't go into X?

The numerator part can have any value of x, so there are no restrictions. The denominator part, you know you cannot have zero in the denominator. If you do, the entire formula will be invalid. Can you have zero denominator for certain value of X? If there are such number(s), then that's a restriction.

Start from there...
