   1. The problem statement, all variables and given/known data
   
   [tex] \lim_{x→-∞}xe^{x} [/tex]
   
   2. Relevant equations
   
   
   
   3. The attempt at a solution
   
   L'Hopital's rule maybe? I solved a lot of problems today, just no idea how to get past this one. Any hints?

   Write the limit as
   [tex]\lim_{x→-∞} \frac{x}{e^{-x}}[/tex]
   Apply L'Hopital's rule.
