    its (2a-1)/(1-2a) =-1 , so -1 is the answer

    here are the steps akash_809 has used \[h(x)=\frac{x-1}{1-x}\]\[h(2a)=\frac{2a-1}{1-2a}\]\[\qquad\quad=\frac{-(1-2a)}{1-2a}\]\[\qquad\quad=\frac{-\cancel{(1-2a)}}{\cancel{1-2a}}\]\[\qquad\quad =-1\]

    the function gives the same value for all inputs (except x=1, which has indeterminate value )
