    Here,there are 2 ways, 1) you'll have to check right hand and left hand limits separately 2) make use of the fact that [x] + [-x] = -1

    Using 2nd one quickly guides you towards the answer. 1st method also isnt lengthy enough, try it.

    for x->2- , we have -3 for x->2+ , we have again -3 but when x=2 , we have -2.

    the 2nd fact is only valid if x is not an integer, which is not the case here.

    To sahi hai fir, -3 hoga, mere method se , ya fir book ke method se. kyunki exact value pe nahi check kar rahe to fir 2nd method laga sake hai, -3 aa jayega.
