Draw a curve with its equation

[Veronique Darmendrail]

Hello
How can I get a graph with the curve when I have the equation of the curve like y=a + bx + x^2 ?With R it's with the "curve" command but I don't find for stata.
Thanks a lot for your help.

See -help twoway function-. You might do something like:

twoway function  y=5 + 10*x + x^2
