1.

If f(x, y) = x2 - 4xy + y' + 4y, find the extrema of fSketch the region R bounded by the graphs of the given equations. Assume that f is continuous and express [[223 + 43; (JUL provided that R consist of the region in the my plane bounded by y = x2 and R g = 2:5. Evaluate the integral and express the answer as a fraction
