Find the intervals in which the following functions are (a) increasing (b) decreasing : f(x)=x^(3)-6x^(2)+9x+15

Find the points of local maxima or local minima,if any,using first derivative test,and local maximum or local minimum of f(x)=x^(3)-6x^(2)+9x+15

Find the local maxima and local minima, if any, of the followig functions. Find also the local maximum and the local minimum values, as the case may be : f(x)=x^(3)-6x^(2)+9x+15

Find the points at which the functions f(x) = x^(3) - 6x^(2) + 9x + 15

Find the maxima or minima of f(x) = x^(3) - 6x^(2) + 9x + 15 .
