Rewrite the Equation in Standard Form $$y = x ^ { 2 } - 14 x + 39$$

Multiple Choice

Rewrite the equation in standard form. Determine whether the parabola is horizontal or vertical, the direction it opens,
and the vertex.
- $$y = x ^ { 2 } - 14 x + 39$$

A) $y = ( x + 7 ) ^ { 2 } + 10$
vertical, opens upward, vertex $( - 7,10 )$
B) $y = ( x + 10 ) ^ { 2 } + 7$
vertical, opens upward, vertex $( - 10,7 )$
C) $y = ( x - 10 ) ^ { 2 } - 7$
vertical, opens upward, vertex $( 10 , - 7 )$
D) $y = ( x - 7 ) ^ { 2 } - 10$
vertical, opens upward, vertex $( 7 , - 10 )$
