![\begin{displaymath}F(z) = \sum_{k=-\infty}^\infty f[k] z^{-k}
\end{displaymath}](img71.png)
Let us consider the 
transform of ![$f[k] = -\gamma^k u[-(k+1)]$](img72.png)
(draw the picture). We find
Compare with ![$g[k] = \gamma^k u[k]$](img74.png)
.
What gives? Must specify region of convergence for these.
In the most general case, we have
transform of
(draw the picture). We find .
