1. Always positive
2. Asymptotic to the x-axis
3. Gets big very fast
4. has an intercept at
Exponential growth:

and . Starts very small at a large magnitude negative number, passes through , and then quickly increases without bound.

Exponential decay:

and . Starts very large on the left of the -axis, decreases until it passes through , and then then decreases until asymptotic to the positive -axis.
