3. 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:
(v)
Givrn function is
Hence 1 and 3 are critical points
Now, we use the second derivative test
Hence, x = 1 is a point of maxima and the maximum value is
Hence, x = 1 is a point of minima and the minimum value is
