# Math Help - Proving this asymptote?

1. ## Proving this asymptote?

How can I prove this? I don't understand the problem....Here it is:

2. They are asking at $\displaystyle x \to \infty$

if the slope of the curve is equal to the slope of the asymptote.

So first find the slope of the asymptote, then find $\displaystyle y'(\infty)$

you may need to use some properties of limits.

Are they equal?
