Graph Rational Function

  • when graphing a rational function (y = 1/x) i get a line crossing the asymptote (y axis for this function...)


    ?how can i stop this...?


    ???


    thank you.

    Well


    Obviously, dividing by zero is the cause.


    You could delete A12:B12.


    Or click once on the line chart, and again on the part between -1 and 0 on the axis. Format that part of the line invisible. Do the same for the part between 0 and 1.

    thank you...! (i deleted x = 0)...


    ?could you explain further about the line chart and make invisible...?


    and what is the best way to show the y axis going (vertically) through the origin...?


    thank you...!

    If you want to see the asymptotic behavior of rational functions, you need to plot for values of x that exponentially approach the poles from either side (i.e., not plot through them).
