The function are .

The denominator of f is zero when .

So, the domain of f is all real numbers except .

The domain of g is all real numbers.

The domain of f is all real numbers except and the domain of g is all real numbers.

The function are .

To find any vertical asymptotes, first factor the numerator and denominator as follows.

The simplified function, has no denominator.

So, the vertical asymptote is none.

Because by setting the denominator equal to zero and solve the resulting equation for x.

The simplified function, and the vertical asymptote is none.
