Which of the following graphs represents local minima at x = a ?
As we have learned
Local maximum and Local minimum -
Let y = f(x) be the given function then is a point of local maximum if there exists an open interval containing such that
for all values of x lying in that interval and for then it is local minimum in fig and at
Here (D) is the only case where we will have an interval in the neighbourhood of x= a which contains x=a and
