Consider the function
This function has an absolute minimum value equal to:
which is attained at
and an absolute maximum value equal to:
which is attained at
I know I do the derivative and then set it to zero. But then what? Thanks

$\displaystyle \displaystyle f'(x)=e^{-6x}-6xe^{-6x}=e^{-6x}(1-6x)=0$
Since e to a power can't be 0, we only look at the $\displaystyle \displaystyle 1-6x=0\rightarrow x=\frac{1}{6}$
Now, use the test to see if x and the end points to see if what are your local mins and maxs.
