Dear kapil ,


for addition find the domians of both the terms and intersect them to get the final domain .


here first term has doamin R as al values of x are possible. for second term ,


1+x/ 2x  must lie between -1 and 1 . 


               1 ≥   1+x/ 2x ≥  -1     solving will get , R - { 0}.  awhich is also the final answer.
