For example f(x)=(x^4+1)/(x^2+1) is defined everywhere, thus no vertical asymptotes (for rational functions vertical asymptotes always come with undefined points at that place e.g. x/(x-1) at 1). In fact the provided f(x) doesn't have horizontal nor oblique asymptotes either since lim x->±inf of f'(x) doesn't equal 0 nor any other constant value. As far as I can tell, this is enough to show, that one particular rational function has no asymptotes. Thus you are incorrect.

This is a controversial take but logarithms are both a blessing and a curse. They are a blessing because they can make certain calculations easier and sometimes when you are graphing, the relation between two variables can be more easily seen if you use a logarithmic plot. They are also a curse because certain properties make them hard to deal with. For example the complex logarithm is multi valued which is always a nuisance (it’s also multi valued in the context of Lie Groups), another annoying property is that logarithms tend to infinity but grow slower than all power functions, which is a nuisance in perturbation problems.
