Suppose you have the following function : f ( x, y,z)= 2 . x2 -6 .x. y+8.x.z+9.x-6.12+ 10.y.z+6.y+5-z2-6.z Snipping Tool is moving... We want to find the "extremum" points for the function. In a future update, Snipping Tool will b new home. Try improved features and Put the F.O.C in the form A y = with Snip & Sketch (or try the shortcut Windows logo key + Shift + S). How many rows does the matrix A have Try Snip & Sketch How many columns does the matrix A have What is the matrix A what is the optimal value for x what is the optimal value for y what is the optimal value for z What is the Hessian of this probem Is the Hessian Onegative semidefinite Onegative defnite Opositive definite Onegative defnite Oindefinite the extremum you found is an OLocal maximum Oglobal minimum Oglobal maximum Olocal minimum Oinflection point
