(A)

(B) Separate    to  get  ,  Since   −(−1)   =   1   +   C   implies that

C   =   0,  the solution    is  .

This    function    is  discontinuous   at  x   =   0.  Since   the particular  solution    must

be   differentiable  in  an  interval    containing  the     initial     value  x    =   1,  the

domain  is  x   >   0.
