# How do you find the vertical, horizontal and slant asymptotes of: F(x)=e^x?

This function only has a horizontal asymptote at $y = 0$
There are no real values of $x$ for which ${e}^{x}$ would be $0$ or less, so the $X$ axis or $y = 0$ is a horizontal asymptote.
A function may only have a vertical asymptote in points which are outside of its domain. So if the domain is $\mathbb{R}$, then there cannot be any vertical asymptotes.
