Why does Geogebra draw the function $f(x)=\frac{x}{x}$ as if it were the function $f(x)=1$? I noticed that Wolfram Alpha and Google also draw the former as if it were the latter. Is it possible to fix this?

    How do you expect the only difference, a hole at $x=0$, to be drawn? At Desmos, you can only see the hole when you put the cursor right on it. – Torsten Schoeneberg Nov 23 '19 at 23:02

    Most graphing software plots a bunch of points and connects them. – Rushabh Mehta Nov 23 '19 at 23:03
  • Well, I expect some kind of circle in order to make explicit that the function is undefined if $x=0$. – pompeu Nov 23 '19 at 23:10
  • If anyone knows of a way to at least fix it "in post" so that I can show my calc students a function in GeoGebra with an obvious removable discontinuity, I'd love to hear about it! Trying to add a tiny circle to the graph ruined an otherwise pleasant day for me a while back. –  Nov 23 '19 at 23:13
