uestion 2 (1 point) Consider the function f given by z = f(x, y) = 16In(x +y) - 3x2 - y. Suppose that the variables x and y change from the initial values (Xo, yo) = (0,4) to the new values (X1, y1) = (-1,6). a) Find the total differential of fand evaluate it using the given information about the values of (x, y). The value of the evaluated total differential is: A b) Find the second order total differential of f and evaluate it using the given information about the values of (x, y). The value of the evaluated second order total differential is: A/
