The circle or ellipse shown in the calculator-generated graph was created using function mode with a square viewing window. What are the two functions $y_{1}$ and $y_{2}$ that were used to obtain the graph whose equation is given?
-$(x-1)^{2}+(y-1)^{2}=1$

A) $y_{1}=-1+\sqrt{1-(x-1)^{2}}, y_{2} =-1-\sqrt{1-(x-1)^{2}}$
B) $y_{1}=-1+\sqrt{1-(x-1)^{2}}, y_{2}=1-\sqrt{1-(x-1)^{2}}$
C) $\mathrm{y}_{1}=1+\sqrt{1-(\mathrm{x}-1)^{2}}, \mathrm{y}_{2}=1-\sqrt{1-(\mathrm{x}-1)^{2}}$
D) $y_{1}=1+\sqrt{1-(x-1)^{2}}, y_{2}=-1-\sqrt{1-(x-1)^{2}}$
