Find and classify all relative extrema for The function given is:\[ f(x, y) = x^2 + y^2 + 2xy. \][Hint: If the second partial test is inconclusive, find another way to classify the extrema.]This function includes terms \(x^2\), \(y^2\), and \(2xy\). The hint suggests that sometimes the second derivative test, typically used to determine local maxima, minima, or saddle points, may not give a clear result. In such cases, alternative methods for classifying critical points should be explored.

Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma.t Over a period of months, an adult male patient has taken nine blood tests for uric acid.
