#9, Again, f(x,y) = x² + y² = xy-3x Find the absolute minimum and absolute maximum of fon the region R bounded y=3-x, x = 0, y=0. ,x=0, by

Find the absolute minimum and absolute maximum of the function f(x, y) = x^3 – 2y^3 + 3y + (x – 1)^2 over the closed region formed by the triangle with vertices at (-1, -1), (2, 0), and (0, 2).

Find the global maximum and minimum of f if there is • f(x, y) = y,2x² + y²2 = . = • f(x,y, z)=x+y-z, x² + y² +z² = 81 .

Suppose that f(x, y) = 3x* + 3yª – 2xy Then the minimum is

Consider the function f(x, y) = 3x^2 + 4xy + 2y^2 - 12x - 16y . Find the critical points of  f  and determine whether each is a local maximum, local minimum, or saddle point.

what is the maximum of the function g(x,y) = (x2 + y - 11)2 + (x + y2 - 7)2 over the region 0 ≤ x ≤ 5 and 0 ≤ y ≤ 5? At which values of x and y is it at maximum?

F(x,y)= 4xy-x^3-2y^2 C. Find the relative minimum and maximum values of F SHOW ALL WORK!!! thank you:)

How do I find the local maximum and local minimum of f'?

Find the absolute minimum and absolute maximum of f(x, y) = 192x³ + y²(1 - 4x) on the triangle with vertices (0,0), (4,2) and (-2,2).

Find the absolute maximum and minimum values of f(x, y) = 4xy^2 − x^2y^2 − xy^3 on the closed triangular region in the xy-plane with vertices (0, 0), (0, 6), and (6, 0).
