    Graphs of linear rational functions

    SL AA 2.8

    A linear rational function has the form

    f(x)=cx+dax+b​


    When the denominator is zero the graph will have a vertical asymptote:

    cx+d=0⇒x=−cd​🚫


    And as x gets very large, the +b and +d can be ignored:

    y=f(x)≈cxax​=ca​🚫


    So there is a horizontal asymptote at y=ca​.


    Example

    Find the equation of the asymptotes of x−32x+1​.


    The vertical asymptote is x=3, and the horizontal asymptote is y=2.
