Please solve the following Real Analysis problem...you can write by pen and paper and upload the photo, but please explain the solution in more detail..(earlier answer is not very clear)..please explain everything step by step..

Let f : R² → R² be the function
f(x, y) = (x + 2y, (x + y)³ + x + y +1).
Then f has an inverse g = f-1 : R² → R? that is everywhere differentiable. Use this information to
compute Dg(0, 1).
