(there is an option that there is no Local minimum or Maximum point in this Function)

BUT i need to show the way.

Set the derivative equal to zero: .

Therefore, hasmaximum or minimum.*no*

i think you mistake with Absolute minimum and Absolute maximum .

BUT to find Local minimum or Maximum we not must that the derivative will equal to zero.

but still thanks about your answer.
