Answer:
21
Step-by-step explanation:
(7x2)+(1.5x2)+(2x2)
Answer:
A :)
Step-by-step explanation:
has critical points wherever the partial derivatives vanish:
Then
- If , then ; critical point at (0, 0)
- If , then ; critical point at (1, 1)
- If , then ; critical point at (-1, -1)
has Hessian matrix
with determinant
- At (0, 0), the Hessian determinant is -16, which indicates a saddle point.
- At (1, 1), the determinant is 128, and , which indicates a local minimum.
- At (-1, -1), the determinant is again 128, and , which indicates another local minimum.
