Find the Asymptotes, domain, and range

Question

find the asymptotes, domain, and range of f(x)=1/x-1

Answer 1

The vertical asymptote occurs at x=1 since this will make the denominator of the fraction equal to zero which makes the expression undefined

The domain is all real numbers except x=1

The range is all real numbers except y=0 which is the horizontal asymptote
