Determine the Two Equations Necessary to Graph the Horizontal Parabola $$x - 4 = ( y - 5 ) ^ { 2 }$$

Multiple Choice

Determine the two equations necessary to graph the horizontal parabola using a graphing calculator.
- $$x - 4 = ( y - 5 ) ^ { 2 }$$

A) $y = \sqrt { x - 4 } + 5$ and $y = 5 - \sqrt { x + 4 }$
B) $y = \sqrt { x + 21 }$ and $y = - \sqrt { x - 29 }$
C) $y = \sqrt { x - 4 } + 5$ and $y = 5 - \sqrt { x - 4 }$
D) $y = \sqrt { x - 4 } + 5$ and $y = - \sqrt { x + 4 } - 5$
