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

Multiple Choice

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