y_{1}

and

y_{2}

that were used to obtain the graph whose equation is given?
-

(x-2)^{2}+(y-2)^{2}=1

$The circle or ellipse shown in the calculator-generated graph was created using function mode with a square viewing window. What are the two functions y_{1} and y_{2} that were used to obtain the graph whose equation is given? - (x-2)^{2}+(y-2)^{2}=1 A) \mathrm{y}_{1}=2+\sqrt{1+(\mathrm{x}-2)^{2}}, \mathrm{y}_{2}=2-\sqrt{1+(\mathrm{x}-2)^{2}} B) \mathrm{y}_{1}=\sqrt{1-(\mathrm{x}-2)^{2}}, \mathrm{y}_2=-\sqrt{1-(\mathrm{x}-2)^{2}} C) \mathrm{y}_{1}=2+\sqrt{1-(\mathrm{x}-2)^{2}}, \mathrm{y}_{2}=2-\sqrt{1-(\mathrm{x}-2)^{2}} D) y_{1}=2+\sqrt{(x-2)^{2}-1}, y_{2}=2-\sqrt{(x-2)^{2}-1}$

A)

\mathrm{y}_{1}=2+\sqrt{1+(\mathrm{x}-2)^{2}}, \mathrm{y}_{2}=2-\sqrt{1+(\mathrm{x}-2)^{2}}

\mathrm{y}_{1}=\sqrt{1-(\mathrm{x}-2)^{2}}, \mathrm{y}_2=-\sqrt{1-(\mathrm{x}-2)^{2}}

\mathrm{y}_{1}=2+\sqrt{1-(\mathrm{x}-2)^{2}}, \mathrm{y}_{2}=2-\sqrt{1-(\mathrm{x}-2)^{2}}

y_{1}=2+\sqrt{(x-2)^{2}-1}, y_{2}=2-\sqrt{(x-2)^{2}-1}
