What is the domain and range of #e^x#?

Answer 1
Every exponential function has domain #(-oo, oo)# and range #(0, oo)# For base greater than #1# the graph is: graph{y=e^x [-12.97, 15.52, -5.67, 8.57]}
For base, #b# with #0 < b < 1#, the graph looks like:

graph{y=e^(-x) [-12.58, -5.646, 4.355, -7.43]}

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
