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

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. $$y = - 2 x ^ { 2 } - 4 x$$
