FindRoot s all

y[u_,c_]=c^u-u^c-1 ;
Plot[y[x,2],{x,-5,5}]; FindRoot[y[x,2]==0,{x,-5,5}];
" Solution settles to a value outside the interval
of roots of its derivative (humps and valleys),it may be 
the problem of Newton-Raphson diverging tangets.How to
capture all roots [in this case {x -> 0, 1}] ? It should be 
valid for all c."
