[ROOT] How to get the maximum and minimum of a function

Hello Rooters

suppose I define a function like

TF1* fun=new TF1("fun","[0] + [1]*x + [2]*x*x",0,1000);

with three parameters that are given later from input (e.g. a file).
So how can I get the minimum and the maximum value (or position) of this
function within its defined range (here: 0 to 1000) ?


Cheers
