Rewrite the Equation in Standard Form $$y = - 3 x ^ { 2 } + 72 x - 441$$

question 24

Multiple Choice

Rewrite the equation in standard form. Determine whether the parabola is horizontal or vertical, the direction it opens,
and the vertex.
- $$y = - 3 x ^ { 2 } + 72 x - 441$$

• A) \(y = ( x + 12 ) ^ { 2 } - 9\)
• vertical, opens downward, vertex \(( - 12 , - 9 )\)
• B) \(y = ( x - 12 ) ^ { 2 } - 9\)
• vertical, opens upward, vertex \(( 12 , - 9 )\)
• C) \(y = ( x + 12 ) ^ { 2 } - 9\)
• vertical, opens upward, vertex \(( - 12 , - 9 )\)
• D) \(y = ( x - 12 ) ^ { 2 } - 9\)
• vertical, opens downward, vertex \(( 12 , - 9 )\)
