## Homework Statement

I have to find the min and max of this function using derivatives:

(e^(-x)) - (e^(-2x))

## The Attempt at a Solution

f'(x) = -e^(-x) + 2x(e^(-2x))

So now i set that to zero, and I get...

2x(e^(-2x)) = e^(-x)

And at this point I have no idea what to do. If you divide e^-x by e^-2x can u do something with the exponents?
