Answer:
The limit as t approaches infinity of e^-t = 0 because e^-t can be written as 1/e^t, and as you increase e^1 the number gets bigger and bigger, and if you divide 1 by a huge number the answer approaches zero.
Step-by-step explanation:
The graph of e^-t is attached, as you can see when you approach infinity the limit approaches zero.
