Graphing reciprocals of quadratic functions

Steps to graph the reciprocal of a function:
1) Plot a horizontal asymptote at $y=0$
2) Plot vertical asymptote(s) equate the original function to 0; solve for $x$
3) Plot y-intercept(s) $\frac{1}{\text {y-intercept(s) of the original function}}$
4) Plot invariant points: equate the original function to +1 and -1; solve for $x$
5) Plot $\frac{1}{\text {vertex of the original function}}$
6) Place your pen at the invariant points, then smoothly move away while tracing along the asymptotes!
