Find the maximum of a function from its transform

Hi All,

I'm trying to find the maximum of a function f, but all I have is the
Fourier transform T(f). Computing the inverse transform of T(f) to
obtain f is proving to be very complicated. If that was possible, I
would simply solve for f ' = 0 to find the maximum of f. Now since that
is not an option, I'm wondering if there is an equivalent method in the
transform domain using T(f). Any help is greatly appreciated.

Thx
