Removable discontinuity in negative x
When using geogebra cas if I plot for example f(x)=(x-3)/((x-3)(x+1)) it correctly shows the eliminable discontinuity at x=3.
If instead I plot f(x)=(x+3)/((x+3)(x+1)) it does not show the discontinuity at x=-3.
I've checked and it seems to happen with all the eliminable discontinuities in negative x's.
I'm working on windows 10 and chrome but I have also checked in the Geogebra Cas app for the mobile phone.
Thanks for your great work!
