The hyperbola shown in the calculator-generated graph was graphed in 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?
-$\frac{x^{2}}{49}-y^{2}=1$

A) $y_{1}=\sqrt{x^{2}-49}, y_{2}=-\sqrt{x^{2}-49}$
B) $y_{1}=\sqrt{x^{2}+49}, y_{2}=-\sqrt{x^{2}+49}$
C) $y_{1}=\sqrt{\frac{x^{2}}{49}-1}, y_{2}=-\sqrt{\frac{x^{2}}{49}-1}$
D) $y_{1}=\sqrt{\frac{x^{2}}{49}+1}, y_{2}=-\sqrt{\frac{x^{2}}{49}+1}$
