    you plug in the critical values found by f'(x) if f''(x) > 0 then its a minimum if f''(x) <0 then its a maximum if f''(x)=0 it is inconclusive and you have to do either the first order test or go into third order derivatives to determine whether it is a minimum, maximum or inflexion

    The critical values being where f'(x) = 0
