Graph Rational Function f(x)=-6/(x^2+x-12) Using Vertical & Horizontal Asymptotes, x- & y-intercepts

The rational function f(x)=-6/(x^2+x-12) can not be simplified so there are no holes. The function is then examined to find y-axis symmetry, origin symmetry, vertical asymptotes, horizontal asymptote, x-intercepts, and y-intercept. The function is then graphed and two more points are found to complete the graph.
