Question

By completing the square, write the given equation into the standard form, and then identify the vertex, focus, and directrix of the parabola. Also, graph the parabola in a rectangular coordinate system.
x² + 10x - 12y + 13 = 0

x² + 10x - 12y + 13 = 0

Accepted Answer

Standard form: (x +5)² = 12(y +1); Vertex: (-5, -1); Focus: (-5, 2); Directrix: y = -4

Graph of a parabola with vertex (-5, -1), focus (-5, 2), and directrix y=-4.

Answer

Standard form: (x -5)² = 12(y +1); Vertex: (5, -1); Focus: (5, 2); Directrix: y = -4

Graph of a parabola with vertex (5, -1), focus (5, 2), and directrix y=-4.

Answer

Standard form: (x -5)² = 12(y -1); Vertex: (5, 1); Focus: (5, 4); Directrix: y = -2

Graph of a parabola with vertex (5, 1), focus (5, 4), and directrix y=-2.

Answer

None of these
