I have to find the domain, range, vertical/horizontal asymptote and discontinuities, if any, what kind; removable to or continuous.

I know the vertical asymptote is -2 but how do i find the horizontal ones. i graphed it and the graph did have multiple horizontal asymptotes.

Thank you.

(new addition)

$\displaystyle \frac{7x}{\sqrt{x^2-10}}$

same things
