Use the Equation of the Parabola in Standard Form $y = a ( x - h ) ^ { 2 } + k$

question 57

Multiple Choice

Use the equation of the parabola in standard form $y = a ( x - h ) ^ { 2 } + k$ to determine the coordinates of the vertex and the equation of the axis of symmetry (complete the square if necessary) . Then graph The parabola. $$y = - 2 x ^ { 2 } - 4 x$$

• A) vertex: \(( 1 , - 2 )\); Line of symmetry \(x = 1\)
• B) vertex: \(( - 1,2 )\); Line of symmetry \(x = - 1\)
• C) vertex: \(( - 1 , - 2 )\); Line of symmetry \(x = - 1\)
• D) vertex: \(( 1,2 )\); Line of symmetry \(x = 1\)
