Math Software  -> Graph Function (Graph Calculus) -> Math Functions -> Graphing Rational Functions

Function Grapher and Visual Calculus have the ability of graphing rational functions. The following figure shows the effect of graphing rational function. The function of the curve in the graph is y=(x^3+x-1)/(x+3).

The following figure shows the effect of graphing rational function. The function of the curve in the graph is y=x+1/x.
