Question 1187610:  Find the absolute extrema of the function on the closed interval.
 
f(x) = x^3 − 3/2x^2,    [−3, 4]
 
maximum    	(x, y)	 = 	
 
 
Find the absolute extrema of the function on the closed interval.
 
y = 3x^2/3 − 2x,    [−1, 1]
 
maximum    	(x, y)	 =

You can  put this solution on YOUR website! Find the absolute extrema of the function on the closed interval.
 
   ,    [−3, 4]
The absolute extrema are either points at which the derivative is 0 or
undefined, or the endpoints of the interval, -3 or 4.
    which we set = 0
   
   
 
Points where derivative is 0 are (0,0) and (3,13.5)
Endpoints:
 
So the absolute maximum point is (4,40)
and the absolute minimum point is (-3,-40.5).
 Find the absolute extrema of the function on the closed interval.
y = 3x^2/3 − 2x, [−1, 1]
Do it the same way all by yourself.  This time one of the absolute extrema
will be an an endpoint and the other at a point where the derivative is 0.
