# How to plot this function

I want to plot functions (using some software, any recommendations?) that looks like this below. Could someone suggest equations of functions that would look like the graph below?

There are many of them: I have started to use Geogebra. –  user21436 Apr 4 '12 at 14:01
Thanks, could you give me an example? –  Gary Apr 4 '12 at 14:01
Have you tried: gnuplot (free), mathematica, matlab, ...? The functions you list could be more or less anything - how about $b(x) = (x/10)^2, h(x) = 1+b(x), g(x) = 2+b(x), f(x) = 3+b(x)$? –  Johannes Kloos Apr 4 '12 at 14:09
Thanks Johannes! –  Gary Apr 4 '12 at 14:51

Besides the excellent suggestions made by Johannes Kloos

Have you tried: gnuplot (free), mathematica, matlab, ...? The functions you list could be more or less anything - how about $b(x)=(x/10)^2$, $h(x)=1+b(x)$, $g(x)=2+b(x)$, $f(x)=3+b(x)$?

I'll add that fooplot is free, runs in a browser, and is very easy to use:

You can also do the plots by using MAPLE as follows:

[> with(plots):
[> b := proc (x) options operator, arrow; (1/100)*x^2 end proc:
[> multiple(plot, [b(x), x = 0 .. 10, y = 0 .. 5,color and 0 .. 5,color = red, thickness = 3], [b(x)+1, x = 0 .. 10, y = 0 .. 5, color = green, thickness = 3], [b(x)+2, x = 0 .. 10, y = 0 .. 5, color = blue, thickness = 3], [b(x)+3, x = 0 .. 10, y = 0 .. 5, color = black, thickness = 3]);

@amWhy: Yes I wish I could go. Thanks, I am well but exhausted cause of 8 hours teaching. :-) –  Babak S. Oct 27 '13 at 18:10
@amWhy: Honestly, I am addicted to be here Amy. Thanks for your supporting and warming words my dearest friend. ;-) –  Babak S. Oct 27 '13 at 18:32
