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

question 131

Multiple Choice

Determine the two equations necessary to graph the ellipse with a graphing calculator.
- $$\frac { x ^ { 2 } } { 9 } + \frac { y ^ { 2 } } { 64 } = 1$$

• A) \(x = \sqrt { \frac { 192 - x ^ { 2 } } { 8 } }\) and \(x = - \sqrt { \frac { 192 - y ^ { 2 } } { 8 } }\)
• B) \(x = \frac { 3 \sqrt { 9 - y ^ { 2 } } } { 64 }\) and \(x = - \frac { 3 \sqrt { 9 - y ^ { 2 } } } { 64 }\)
• C) \(y = \frac { 8 \sqrt { 9 - x ^ { 2 } } } { 3 }\) and \(y = - \frac { 8 \sqrt { 9 - x ^ { 2 } } } { 3 }\)
• D) \(y = \frac { 8 \sqrt { 9 - x ^ { 2 } } } { 9 }\) and \(y = - \frac { 8 \sqrt { 9 + x ^ { 2 } } } { 9 }\)
