Explain why the function is differentiable at the given point. f(x, y) = 2 + x ln(xy โ 5), (2, 3) the partial derivatives are fx(x, y) = correct: your answer is correct. and fy(x, y) = correct: your answer is correct. , so fx(2, 3) = 6 correct: your answer is correct. and fy(2, 3) = 4 correct: your answer is correct. both fx and fy are continuous functions for xy > 3 incorrect: your answer is incorrect. and f is differentiable at (2, 3). find the linearization l(x, y) of f(x, y) at (2, 3). l(x, y) = incorrect: your answer is incorrect.
