If a a is negative the maximum value of the function is f b 2a f - b 2 a. Y x2 - 6x 9. The function fx x 2 does have a minimum namely at x 0.
The method used to find the absolute extremes of a function depends on the variables that the objective function has and whether or not it is subject to a constraint.
