Graph Rational Function Using Vertical & Horizontal Asymptotes, & Intercepts: f(x)=(x-1)/(x^2-2x-3)

The rational function f(x)=(x-1)/(x^2-2x-3) can not be simplified so there are no holes. The function is then examined to find vertical asymptotes, horizontal asymptote, x-intercepts, and the y-intercept. The function is then graphed and three more points are found to complete the graph.
