Answer:
Step-by-step explanation:
6, 8, 9, 11, 12, 14
14-6=
8
Range: 8
Answer:
-3
explanation:
3/4 times negative 4 = -3
Answer:
8
Step-by-step explanation:
I think I'm not for sure but if not 8 then 9 and no it's not because you add 5+4
The Lagrangian is

with partial derivatives (set equal to 0)





Case 1: If
, then

Then


So we have two critical points,
and 
Case 2: If
, then in the first equation we get

and from the third equation,

Then


but there are no real solutions for
, so this case yields no additional critical points.
So at the two critical points we've found, we get extreme values of
(min)
and
(max)
