Correction: That is not a logarithmic function, but here is how to find the critical numbers for the function.

#### Explanation:

Note that

#= e^x+2e^(-x)-3#

We need to solve

As a first step, try getting rid of negative exponents:

Get a common denomiator, noting that

So now we need to solve:

Again note that

Both are in
