Question

determine value h(2a) for function h(x)=x-1/1-x

Answer 1

i got 2a-1/1-2a=H(x) do i need to do anything else

Answer 2

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

Answer 3

here are the steps akash_809 has used

\[h(x)=\frac{x-1}{1-x}\]\[h(2a)=\frac{2a-1}{1-2a}\]\[\qquad\quad=\frac{-(1-2a)}{1-2a}\]\[\qquad\quad=\frac{-\cancel{(1-2a)}}{\cancel{1-2a}}\]\[\qquad\quad =-1\]
