Real Analysis II Q4
For each of the following, if the Inverse Function Theorem applies to f at c,
find Dg(x, y) both directly and by the Inverse Function Theorem formula. If
the Inverse Function Theorem does not apply to f at c, does (flu)-¹ exist
anyway for some nhood U of c? Justify your answer.
1. Let f: R² → R2 where f(x, y) = (y³, xy) and c = (0, 1).
2. Let f: R²
R2 where f(x, y) = (y³, xy) and c = = (1,0).
3. Let f: R²
R2 where f(x, y) =
(y³, x + y) and c = (0, 1).
4. Let f: R2
R2 where f(x, y) = (y³, x + y) and c = (1,0).
