find the derivative of f(x) = x^3 + 2x^2 - 5x - 6. Find all stationary points of the function.

Calculate the derivative using the standard rules, in particular (x n )' = nx n-1 . f(x)' = 3x 2 + 4x - 5 Stationary points are where the derivative is equal to 0, i.e. all x such that f(x)' = 0, so solving ...
