Question 1

Find the absolute maximum and minimum values of  f(x, y) = xy3 e-(x2 + y2)  on the semi-infinite strip ,  if these extreme values exist.
◦ maximum  ,   minimum  -
◦ maximum  ,   minimum  -
◦ maximum  ,   minimum  -
◦ maximum  ,   minimum  0
◦ no extreme values exist

Question 2

A function  f(x, y, z)  has continuous first partial derivatives at all points in 3-space.  Its restriction to a closed, bounded domain  R  is identically zero on the boundary of  R, but has the values  5  and  -3   at two interior points of  R.  What is the smallest number of critical points that  f  must have in the interior of  R?
