Answer :-
The functions fj are linear,
Then CQ holds for all feasible x^0 so,we may use the linear arc
we may use the linear arc 
Here 
then the linear arc becomes zero
But we cannot consider the linear arc as zero
so we add the value 
The feasible values of 
we are using the linear arc 
i tried my best hope its helpful to you.
Thank you
