@kunal
Do we check local maxima/minima on end points?

maxima value occur  at x= -3

minima value occur  at x= 0

yes , it should be checked on endpoints also as square braces are given in the question .

I don't agree to this point! we don't check local maxima and minima on end points, however we check on end points in the case of absolute maxima/minima.

If you have any links to prove your point it will be a great help!

@vijaycs Please check this. I think it might be helpful for you. Just check the example towards the end. http://mathinsight.org/local_minima_maxima_refresher

Yes ur solution is fine @Vijay [email protected] chalotra at x = -3 , absolute maximum exists not local maxima exists..

after calculating critical points we have differentiate second time to check local maxima and minima .rt habib??

Yes then we have 0 at x = 1 and > 0 at x = 0 ..So clearly x = 0 is a point of minima..But for x = 1 , we need to check further..

It should be  B) without any doubt as in case of local minima or maxima we do not consider the extreme points or points of discontinuity..

Only we check the points using derivatives..That is it..
