A rational function may or may not have a vertical asymptote.

If the domain of the rational function is all real numbers, then there is no vertical asymptote.

Consider the function is \"f\\left.

The domain of the function is all possible values of \"x\".

Re write the expression as \"f\\left.

Cancel common terms.

\"f\\left.

The domain of \"f(x)\" is all real numbers.

The function does not have any vertical asymptote.

Therefore, every rational function does not have a vertical asymptote.
