Find the maximum and minimum values of the function
f(x,y,z)=3x−y−3z subject to the constraints x^2+2z^2=49 and
x+y−z=9. Maximum value is Maximum value is , occuring at
( , , ). Minimum value is , occuring at ( , ,
).
Find the absolute maximum and the absolute minimum of
the function f(x,y) = 6 - x² - y² over the region R = {(x,y) | -2
<= x <= 2, -1 <= y <= 1 }. Also mention the points at
which the maximum and minimum will occur.
a.Find the absolute maximum and minimum for z=xy-x-y/2 over the
region bounded by y=x^2 and y=3x;
b. Find the critical points and critical values for
z=x^2+2y^2-2xy+3x+y+3.
Problem 2
Find the locations and values for the maximum and minimum of f
(x, y) = 3x^3 − 2x^2 + y^2 over the region given by x^2 + y^2 ≤
1.
and then over the region x^2 + 2y^2 ≤ 1.
Use the outline:
INSIDE
Critical points inside the region.
BOUNDARY
For each part of the boundary you should have:
• The function g(x, y) and ∇g
• The equation ∇f = λ∇g
• The set of three equations...
