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

question 28

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 \(( 7 , - 10 )\)
