Answer to Question #8972 in Abstract Algebra for tracey white
find the vertical asympotes, if any, of the graph of the rational function. h(x)=x/(x-1)
Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. For h(x)=x/(x-1) the denominator is x-1. It equals to 0 if x=1. Then x=1 is a vertical asymptote.
