As we have learned

Local maximum and Local minimum -

Let  y = f(x)  be the given function then  x=x_{\circ }   is a point of local maximum if there exists an open interval containing  x_{\circ }  such that  f(x_{\circ })>f(x)

for all values of  x  lying in that interval and for f(x_{\circ })<f(x)  then it is local minimum in fig and at

x=a,x=c\:\:\:Local\:\: maxima

and\:at\:\:x=b,x=d\:\:\:Local\:\: minima

- wherein

 

 Here (D) is the only case where we will have an interval in the neighbourhood of x= a which contains x=a and f(a)< f(x)
