Let f(x, y) = (x + 2)² + (y + 2)². Fill in the blanks. f(-2, –2) = 0 fa(-2, –2) = 0 f(-2, —2) — о f(x, y) = (x + 2)² + (y+2)² is at (-2, –2). differentiable

Please ignore the answer I wrote down and do the question on your own. The last blank you can either wrote "differentiable" or "not differentiable", and the first three blanks you have to write a number. Thank you.
