Q.Let $f(x) = x^3 - 6x^2 + 9x + 15$ . Then $f(x)$ has

local maxima at

x=1

and local minima at

x=3

local minima at

x=1

and local maxima at

x=3

local maxima at both

neither maxima nor minima

The correct solution involves applying the fundamental concept to derive the final value step by step...
