The Hessian matrix (H) takes the following form: H = [] With function f(x, y) = (x² − y)(2x² − y) and initial point (æo, yo)= (3, 2.7), what are the elements of the Hessian matrix? - a=127.80, b=-18.00, c--18.00 and d=127.80. a=2, b=-18.00, c=-18.00 and d=127.80. O a=2, b=-18.00, c=127.80 and d=2. O a 199.80, b=-18.00, c=-18.00 and d=2.
