    For f(x)=x3−3x2f(x) = x^{3} - 3x^{2}, at which value of xx does ff have a local minimum?

    Para f(x)=x3−3x2f(x) = x^{3} - 3x^{2}, em que valor de xx é que ff tem um mínimo local?

    Solution

    Step 1 of 4

    1. 1.f′(x)=3x2−6x=3x(x−2)f'(x) = 3x^{2} - 6x = 3x(x - 2), so the stationary points are x=0x = 0 and x=2x = 2
