Need some advice

Dear friends,
In ROOT I have 3 histos (1 dimensional), h1, h2 and h3.
h1 I fit with some function f and now I would like to subtract
h3 from h2 in which I weight each bin of h3 with the function value of
f in that bin. I.e. result= h3 - f(x)*h2.
Could anyone of you tell me the most effective (c.q. elegant) way to
do this, such that I don't have to change all the code when changing the
function f ?
Thanks in advance,
Nick.
