I know that in Mathematica one can define a function as follows:

f[x_]:=x^2.

The problem is, I get a polynomial from a for loop as an expression p=a*x^n+b*x^(n-1)+.... Now I want to evaluate the polynomial at a specific point. I tried to define a function from the polynomial as follows:

f[x_]:=p

and to evaluate

f[2]

which gives me just the polynomial, not it's value at 2.

How can I evaluate this?

Sincerely,

Nikola
