Determine the Two Equations Necessary to Graph the Horizontal Parabola x=2y2+8x = 2 y ^ { 2 } + 8

Question 168

Multiple Choice

Determine the two equations necessary to graph the horizontal parabola using a graphing calculator.
- x=2y2+8x = 2 y ^ { 2 } + 8


A) y=x82y = \frac { \sqrt { x - 8 } } { \sqrt { 2 } } and y=x82y = - \frac { \sqrt { x - 8 } } { \sqrt { 2 } }
B) y=x82y = \frac { \sqrt { x - 8 } } { 2 } and y=x82y = - \frac { \sqrt { x - 8 } } { 2 }
C) y=x28y = \sqrt { \frac { x } { 2 } - 8 } and y=x28y = - \sqrt { \frac { x } { 2 } - 8 }
D) y=x82y = \frac { \sqrt { x - 8 } } { \sqrt { 2 } } and y=8x2y = \frac { \sqrt { 8 - x } } { \sqrt { 2 } }
