No.

If you understand the idea of limits you can say that e^x approaches 0 as x approaches negative infinity

[tex]\lim_{\substack{x \rightarrow - \infty\\}} e^x = 0 [/tex]

The larger and larger negative numbers you get for x, the closer and closer to zero you will get for e^x. But you can never actually get 0.

For more help, you can draw the graph of [itex]e^x[/itex] , the graph is an increasing function and which approaches zero and -infinity, but never equals zero.
