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?
-$x^{2}+y^{2}=25$

A) $y_{1}=\sqrt{25-x^{2}}, y_2=\sqrt{25+x^{2}}$
B) $\mathrm{y}_{1}=\sqrt{25-\mathrm{x}^{2}}, \mathrm{y}_2=-\sqrt{25-\mathrm{x}^{2}}$
C) $y_{1}=\sqrt{x^{2}-25}, y_{2}=-\sqrt{x^{2}-25}$
D) $y_{1}=\sqrt{25+x^{2}}, y_{2}=-\sqrt{25-x^{2}}$
