5, 6, 7, 8, 2, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 Find the local maximum and minimum values and saddle point(s) of the function. If you have three-dimensional graphing software, graph the function with a domain and viewpoint that reveal all the important aspects of the function.13. f (x, y) = 24 - 2x +y' - 3y Answer + X Maximum f (0, -1) = 2, minima f (+1, 1) = -3, saddle points at (0, 1), (41, -1)
