In Progress
Apologies if this has been raised before. I did a quick google search and couldn't find an issue that matches this.
I'm trying to graph a tanh(x) function using GeoGebra Graphing Calculator, and it seems to only plot the curve for -infinity < x < 355. For x > 355 it returns as undefined.
My eventual goal is to graph tanh(3.5*x) from 0 to 365, but because of the above issue, the curve seems to only be drawn until x = 100.
Attaching a file with the above functions in case its helpful.

The same problem 
It seems OK to me. Please can you post a screenshot showing the problem?
Hi,
Please find attached the screenshot
I graphed y = 100 + tanh(x) so that the curve isn't overlaid on the x-axis, allowing us to easy where the curve ends. You can see that geogebra says that y has an extremum at x = 353.88, which doesn't make sense.
Hope this helps. Happy to provide more information if necessary.
Here is the URL for the above graph. https://www.geogebra.org/gr...
Thanks, got it!

You can use If(x>350,1,tanh(x)) as a workaround
