Determine the Two Equations Necessary to Graph the Horizontal Parabola $$x = 2 y ^ { 2 } + 8$$

question 168

Multiple Choice

Determine the two equations necessary to graph the horizontal parabola using a graphing calculator.
- $$x = 2 y ^ { 2 } + 8$$

• A) \(y = \frac { \sqrt { x - 8 } } { \sqrt { 2 } }\) and \(y = - \frac { \sqrt { x - 8 } } { \sqrt { 2 } }\)
• B) \(y = \frac { \sqrt { x - 8 } } { 2 }\) and \(y = - \frac { \sqrt { x - 8 } } { 2 }\)
• C) \(y = \sqrt { \frac { x } { 2 } - 8 }\) and \(y = - \sqrt { \frac { x } { 2 } - 8 }\)
• D) \(y = \frac { \sqrt { x - 8 } } { \sqrt { 2 } }\) and \(y = \frac { \sqrt { 8 - x } } { \sqrt { 2 } }\)
