Limits 1.9: Vertical asymptotes
When a function approaches +ve infinity or -ve infinity (as the denominator approaches zero from either side) as x approaches to a finite point, then there is or are vertical asymptote(s) to that function.
Note: If x is not approaching to a finite point, regardless of the function growing arbitrarily large, there will be no vertical asymptote.
