This is a example in my book(adsbygoogle = window.adsbygoogle || []).push({});

a rational function like f(x) = [(x+2)(x-5)]/[(x-3)(x+1)] has vertical asymptotes at x=3 and x=(-1)

Is all you do is switch the addition and subtraction signs in [(x-3)(x+1)]?

The same equation has a horizontal asymptotes at y=1, which i cant seem to understand where it came from

The is the best i could explain this, thank you for reading this
