Work Step by Step

Continuing to take the derivative of a polynomial will eventually lead to the term $0$. Therefore, when taking the derivative of the numerator and denominator, the numerator will become zero after a certain amount of derivatives and the denominator will remain as $e^{x}$. Therefore, the limit as $x$ approaches infinity will always be 0.
