Mar 18, 2018 at 2:11	comment	added	Willie Wong		Remark: the question originally asked by the OP asked about functions $\mathbb{R}^2 \to \mathbb{R}$. An edit (by another party?) changed the question to be about $\mathbb{R}^2 \to \mathbb{R}^2$, which is why there are two different flavors of answers below, some addressing the original question, and some addressing the updated one.
