Determine the Two Equations Necessary to Graph the Hyperbola with a Graphing

question 121

Multiple Choice

Determine the two equations necessary to graph the hyperbola with a graphing calculator.
- $$\frac { x ^ { 2 } } { 25 } - \frac { y ^ { 2 } } { 9 } = 1$$

• A) \(y = \frac { 3 \sqrt { x ^ { 2 } - 25 } } { 5 }\) and \(y = - \frac { 3 \sqrt { x ^ { 2 } - 25 } } { 5 }\)
• B) \(y = \frac { 5 \sqrt { \mathrm { x } ^ { 2 } + 25 } } { 3 }\) and \(y = - \frac { 5 \sqrt { \mathrm { x } ^ { 2 } + 25 } } { 3 }\)
• C) \(y = \frac { 5 \sqrt { \mathrm { x } ^ { 2 } - 25 } } { 3 }\) and \(\mathrm { y } = - \frac { 5 \sqrt { \mathrm { x } ^ { 2 } - 25 } } { 3 }\)
• D) \(y = \frac { 3 \sqrt { x ^ { 2 } } - 5 } { 5 }\) and \(y = - \frac { 3 \sqrt { x ^ { 2 } } - 5 } { 5 }\)
