Determine the Two Equations Necessary to Graph the Horizontal Parabola $$\mathrm { x } = 2 \mathrm { y } ^ { 2 } - 7 \mathrm { y } + 3$$

question 492

Multiple Choice

Determine the two equations necessary to graph the horizontal parabola using a graphing calculator.
- $$\mathrm { x } = 2 \mathrm { y } ^ { 2 } - 7 \mathrm { y } + 3$$

• A) \(y = \frac { 7 - \sqrt { 8 x - - 25 } } { 2 }\) and \(y = - \frac { 7 + \sqrt { 8 x - - 25 } } { 2 }\)
• B) \(y = \frac { 7 - \sqrt { 8 x - - 25 } } { 4 }\) and \(y = \frac { 7 + \sqrt { 8 x - - 25 } } { 4 }\)
• C) \(y = \sqrt { \frac { x - 3 } { - 7 } }\) and \(y = - \sqrt { \frac { x - 3 } { - 7 } }\)
• D) \(y = \frac { \sqrt { x - 3 } } { - 7 }\) and \(y = - \frac { \sqrt { x - 3 } } { - 7 }\)
