I have a small problem. There is a function as a numerical solution to an equation with parameters, and I want to compute the derivative of this function, but fail to do so.

f[a_, b_] := x /. FindRoot[Log[x^0.5 + a] == b x, {x, 10}];
Plot[f[a, 2], {a, 1, 5}]
N[D[f[a, b], a, b]] /. {a -> 2, b -> 2}

Could someone give me a hint on that?
