3. (3p.+ 3p. + 2p.) Consider the function g: R2 + R2 given by : 1 - ery , xy) if (x,y) = (0,0) x2 + y2 g(x,y) (0,0) if (x, y) = (0,0). (a) Decide if g is continuous at (0,0). g (b) Decide if the partial derivatives of g exist at (0,0); if the answer is affirmative, then compute them. (c) Decide if g is differentiable at (0,0); if the answer is affirmative, then find Dg(0,0).
