Question

Find the absolute maximum value of the function  . (4 points)

Question 1 options:

1)	-2
2)	1
3)	0
4)	None of these

Answer 1

Is this 4 points on a test or a quiz?

Answer 2

For the first expression the maximum is at (0,0)

To get the maximum for the 2nd expression, take the 1st derivative and set + to zero:

f'(x) = -2x = 0

x = 0

So the absolute maximum is 1 (the limit of the 2nd expression as x--> 0
