Find the stationary points of the function f(x) = x^3 - 27x and determine whether they are maxima or minima

A stationary point occurs when the first derivative of the function = 0. The first derivative of f(x) is df(x)/dx = 3x^2 - 27Setting this to zero gives 3x^2 - 27 = 0 -> x = +/- 3 To find whether it is a m...
