Score: 0 of 2 pts Question Help 15.8.11 The function f(x,y) = 5xy has an absolute maximum value and absolute minimum value subject to the constraint x² + y2 - xy = 9. Use Lagrange multipliers to find these values The absolute maximum value is SHA re b-a. Cryou the box and then click Check An 1
Please box/circle answers Find the extreme values of the function F(x, y) = 3x2 + 5y? on the circle EXAMPLE 2 x2 + y2 = 1. SOLUTION We are asked for extreme values of f subject to the constraint 9(x, y) = x2 + y2 = 1. Using Lagrange multipliers, we solve the equations VF Ug and 9(x, y) = 1, which can be written as fx = 1gx fylgy (x,y) = 1 or as = 2x1 = 2ya x2...
