# Inverse of a Definite Integral or integral transform

Is there a general inversion formula or procedure for an integral of the form (where f is the function being transformed and g depends on the type of transform) $\int$$^{a}_{b}$ f(x) *g(x,$\xi$) dx ?
Inverses are defined in the conventional ways for functionals and integral transforms, respectively.

For instance, for the fourier transform. In the equation above, a=∞,b=-∞, g(x,$\xi$)=$e^{-2πix \xi }$. I know the inverse fourier transform is simple but I am concerned with a general procedure or process.

I am most interested in the cases where a,b=±∞ although a simple inverse for $\int$$^{a}_{b}$ f(x) dx is also something I am curious about.

Feel free to use complex analysis or any other branch of math if it helps to answer the question. Also, you can repost on another site if it will help.
