please help Also, is the function continuous and/or differentiable at (0,0)

Consider the function 12x 2 f (x, y) = 3 12 + x2 if (x, x) # (0,0) 0 if (x, y) = (0,0) Compute the partial derivatives at the origin. (a) (0, 0) = Ox ( b ) dy (0, 0) = (c) Determine whether the following statement is true or false. "The function f(x, y) is continuous at (0, 0)."
