# Rational Functions and Their Asymptotes

This is an html 5 applet to 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) or using the sliders within the graphing area.

a = b =

c = d =

$f(x)=$
