Suppose $x(t)$ has $a=-4b=9x(t)s=js=jROCa$ with $a=-4$ and $b=9.$ Enter the number $of$ the statement below that $is$ true for $x(t).$

The Laplace and Fourier transforms both exist and the Fourier transform CAN $be$ obtained from the Laplace transform $by$ substituting $s=j.$

The Laplace and Fourier transforms both exist and the Fourier transform CANNOT $be$ obtained from the Laplace transform $by$ substituting $s=j.$

The Laplace transform exists but the Fourier transform does not.

The Laplace transform does not exist.
