.

(a)   remains (3-i) inches, if i < 3;  

      if i = 3, remains 0 (same as nothing);

      if i > 3   or i < 0, then the problem makes no sense.



(b)  remains 3 - (i-5) = 8-i  inches, if  5 < i < 8;

     remains 3 inches, if i = 5;

     remains 0 inches, if i = 8;

     if  i < 5  OR  i > 8,  then the problem makes no sense.
