Hi MathGroup!

Can somebody to help me to find a solution of approximation of a function?
I have a function f[x_]:=a*x+b*x^2+c*x^3, where a,b,c are known numbers. I
would like to find a simplier function for f, for example g[x]=c1 x^c2 at an
given interval with specified precision. How can I find the numbers c1 and

Thanks for Help, Zsolt Regaly.
