Domain where D⊂R2→R,(x,y)↦xy{\displaystyle D\subset \mathbb {R} ^{2}\to \mathbb {R} ,(x,y)\mapsto x^{y}} is defined together with its closure  in (R∪{−∞,+∞})2{\displaystyle (\mathbb {R} \cup \{-\infty ,+\infty \})^{2}}. The (horizontal and vertical) real line are compressed to a bounded interval (not to scale)
