Consider the following function. Find the following derivatives. fx(x, y) = f(x, y) = x² + xy + y² + 7y f(x, y) = 1xx(x, y) = fxy(x, y) = (x, y) = Find the critical point. -(C (x, y) = Find the local maximum and minimum values and saddle point(s) of the function. You are encouraged to use a calculator or computer to graph the function with a domain and viewpoint that r all the important aspects of the function. (Enter your answers as comma-separated lists. If an answer does not exist, enter DNE.) local maximum value(s) local minimum value(s) saddle point(s) (x, y) = 100
