The rational function
- Mr Creamer
The Rational Function Play with the sliders to see if you can find a general formula for which asymptote and the x and y intercepts.
Can you show that The horizontal asymptote is y=a/c ? Why? what happens to f(x) when x is very very large? Find the equation of the Vertical Asymptote ... x = ? To find the y-intercept we look at when x=0. f(0) = (a.0 + b)/(c.0 + d) = b/d So the y - intercept is (0,b/d) Find the x-intercept.
