Consistently repairable definition vacant space

Dear Madams and Sirs,

 

I have a question about „Graph“.

Our math teacher told us, by drawing the graph of the function f(x)=2/(x+2), there should be a “consistently repairable definition vacant space” at point (x = 1) and he marked it in the graph with a little circle.

 

Now I tried to repeat this lesson in your program “Graph”. The definition of this function is no problem and the graph is drawn in the same way our teacher has shown us. But the graph is drawn continuous without a space at x = 1.

 

Can you please declare this function to me?

 

Thank you very much for your efforts.

 

Best regards,

Patrick Vogt

I think you have misunderstood something. There is no space at x=1. The
only place the function is not defined is at x=-2 where you see a
vertical asymptote.

I think he means the hole that would be at x=1 if he (she?) defined something
like the almost equivalent function f(x) = 2(x+1)/[(x+1)(x+2)].  To show the
missing point just define a point series with the single point (1, 2/3).  Make
it round and the set the fill color to white.
