Answer:Answer Key. 1.
Step-by-step explanation: Find all critical points of the function f(x, y) = x. 2 y -x. 2 -3xy +. 2y + 5 and determine whether each critical point is a local mini- ... Solution: Compute Vf = <2xy - 2x - 3y, x ... The second equation gives x = 1 or x = 2. ... H(2,4) = [ 6 1. 1 0. ] and its determinant at our critical points: |H(1,-2)| = (-6)(0) - (-1)(-1) = -1 < 0.
