Which of the following is true about the two-sided Laplace transform?

It has no poles for any bounded signal that is non-zero only inside a finite time interval.
The number of finite poles and finite zeroes must be equal.
If a signal can be expressed as weighted sum of shifted one sided exponentials, then its Laplace Transform will have no poles.
It exists for every signal that may or may not have a Fourier transform.
