This expression: $x(t)=[e^{-3t+5}] u(t-1)$.
I am trying to take the Fourier transformation of the above expression.
I know that for $x(t)=[e^{-at}] u(t) \leftrightarrow \frac1{i\omega+a}$.
But, how am I supposed to transform the above expression? It looks similar to the known transformation, but it certainly is not =/
Thanks!
