# Thread: asymptote problem

1. ## asymptote problem

my book doesn't list this one.

lim f(x)=5
x-> a+

a.horizontal asymptote
b.vertical asymptote
c.both
d.neither

(notice it's as x approaches a from the right)

This isn't an asymptote, it's a limit...

And since you're finding the limit of a constant, the limit IS that constant.

It can't be a vertical asymptote because the y-value is constant. So b and c are out. I would say neither because a horizontal asymptote deals with x going to infinity and the function being bounded and this looks just like a one sided limit.
