Q.7 xy Let f(x,y)=x² + y² ; x² + y² = 0 x=y=0 0; f(x, y) is continuous at origin . Then, f(x, y) is discontinuous at origin f(x, y) has removable discontinuity at origin f(x, y) is not differentiable at origin Q.7 xy Let f(x,y)=x² + y² ; x² + y² = 0 x=y=0 0; f(x, y) is continuous at origin . Then, f(x, y) is discontinuous at origin f(x, y) has removable discontinuity at origin f(x, y) is not differentiable at origin
