Rational Functions and Their Asymptotes

This is an app to help you explore the rational function of the form $f(x)=\dfrac{a x+ b}{c x+d}$ by changing the parameters a, b, c and d entering the values into the input boxes (top left). The horizontal and vertical asymptotes are shown in red broken lines as well. You may zoom in and out the whole graph.
