Question

find the critical points of the function of xy^5+x^5y+xy​

Answer 1

Answer:

There is one critical point for z =x^5y+xy^5+xy. Find it awl classify it as a local maximum, local minimum, or a saddle point. (2)Find the critical point(s) of f(x, y) - 1 + (x - y)^2 + (x - l)^2 and classify each as a local maximum, local minimum, or a saddle point.
