Zoom to graph?

I tried my best to find an answer on my own, but unfortunately Google failed...


Is there an easy way to zoom to something like "y=x*(500-x)"? I mean like e.g. in Inkscape where you press "4" and it shows everything on the canvas.

Have you tried this for the given function? Here that zooms to the parabola's tip.

In Inkscape, you are dealing with finite objects on a canvas. Obviously, the graph of y=x(500-x) is infinite so you can't ever zoom to a degree where you can see "all" of the graph.


If you limit the domain (input) of the function, eg.

[command]f(x)=x*(500-x), 0<x<500[/command]

then 'Show All Objects' will indeed show you the complete graph.

As pirsquared said, this curve is infinite... and with infinite curves, what "all curve" means ?

You have to choose yourself range

pirsquared gave you solution to see what you want...

Question : with Inkscape, you can draw function ? and Inkscape chooses the "good" range ?? for all functions ???
