Determine the Two Equations Necessary to Graph the Horizontal Parabola $$x + 1 = ( y + 8 ) ^ { 2 }$$

Multiple Choice

Determine the two equations necessary to graph the horizontal parabola using a graphing calculator.
- $$x + 1 = ( y + 8 ) ^ { 2 }$$

A) $y = \sqrt { x + 9 }$ and $y = - \sqrt { x + 9 }$
B) $y = \sqrt { x - 7 }$ and $y = - \sqrt { x - 7 }$
C) $y = \sqrt { x + 1 } - 8$ and $y = - \sqrt { x + 1 } - 8$
D) $y = \sqrt { x + 1 } - 8$ and $y = - \sqrt { x + 1 } + 8$
