comment Tree-like nesting of function
Any idea why this fails when the interval is larger e.g. sol[{}, {-100, 100}] (*{0., 3.2, 3., -3., -1., -2.}*) ?

comment Tree-like nesting of function
Finding roots was actually just the first example that came to my mind to illustrate the question (and Roots would only work for polynomials and not for any arbitrary functions )

comment Issue with FindRoot and initial value
I just tried your function findAllRoots and compared it with the results of FindRoot. What I noticed: for f= 300*10^-3 the root I am look for is at 1046.45 (confirmed by looking at a plot of c in that region). Mathematica's own FindRoot does not even find that one if i give it as initial value. Your function however find's the Root but still misinterpreters some other values where c -> Infinity as Roots. Try findAllRoots[c[k, 300*10^-3], {k, 500, 1200}, "ShowPlot" -> False]. Any suggestions why that happens?

comment Issue with FindRoot and initial value
The issue is that the position of the root varies with my input parameters (especially f). I use k within another function called d(f) which is a deflection/force-relationship. Because of the jumpiness of FindRoot I can't obtain a smooth continious defection/force-relationship.

comment Retrieve Options from function other than graphics objects
The output for Options[Unevaluated@f[0, "Amplitude" -> 2]] I'd like to get is {"Amplitude" -> 2, Frequency ->1}

I expected HoldAll to do the trick, but it doesn't

I should have clarified that I want to use OptionsPattern, see the edit in my question

Combine this with the answer from Simon Woods and this is some serious application for the new wolfram programming cloud:D
