Use Lagrange multipliers to find the maximum and minimum values of the function subject to the given constraint. f(x, у) 8x2 + 8y2; xy = 1 Step 1 We need to optimize f(x,y) = 8x2 + 8y2 subject to the constraint g(x, y) = xy = 1. To find the possible extreme value points, we must use Vf = 1Vg. We have Vf = ( 16x, 16 and Vg = 1 1
