MATHEMATICA: How to get numeric result from FindRoot[]?

If I have a function f[], and try to find the roots with it with
FindRoot[], I'm getting a result like:

{x -> 0.49434343}

How can I get the numeric part only (i;e 49434343), so I can plot a
graphs showing the location of the roots?

I did post this earlier, but it seems to have to /dev/null.
