We have critical points whenever both partial derivatives vanish:



The Hessian is


At (0,0), we have

, so (0,0) is a saddle point.
At (-1, -1), we have

and

, so (-1, -1) is a local minimum.
At (1, 1), we have

and

, so (1, 1) is also a local minimum.
The only number all of these numbers can be divided by is 2. Therefore, the GCF is 2
Answer: i think its true
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
since it's multiplication the largest result is the largest integer you have times the second largest integer you have(or itself but not in this case) and the smallest result is the smallest integer you have times the second smallest integer.
so 15 (the smallest result) should be dividable by the smallest integer and 200 (the largest result) should be dividable by the largest integer and if you look at the choices you can see it must be B
