SUMMARY

The forum discussion focuses on solving optimization problems using the Lagrange multiplier method. The specific problem involves minimizing the function f(x, y, z) = x² + y² + z² - 6x - 3y - z under the constraint g(x, y, z) = 11 - 2x - y - z = 0. Participants emphasize the necessity of applying the gradient condition ∇f(x, y, z) = λ∇g(x, y, z) to find the optimal values of x, y, and z, as well as the corresponding Lagrange multiplier λ.

Find the values of x, y and z that minimize the function f ( x, y , z)= x^2 + y^2 + z^2- 6x- 3y -z subject to the constraint 11-2x-y-z= 0

x=....

z=.....

f = ....

λ=.....

dont know what do do

thank you

This problem is set up for Lagrange multiplier method. What does that stipulate?
 
Remember your Lagrange multiplier method.

[tex]\nabla f(x,y,z) = \lambda \nabla g(x,y,z), g(x,y,z)=0[/tex]
