Find the local maxima and local minima, if any, of the following functions. Find also the local maximum and the local minimum values, as the case may be:



Now, g’(x) = 0



=


x2 = 4


x = �2


Since x > 0, we take x = 2




Then, by second derivative test,


x = 2 is point of local minima and local minimum of g at x = 2 is
