Answer:
D
Step-by-step explanation:
This is a vertical opening parabola, since the focus is above the vertex on the axis of symmetry x = 2
The standard form of a vertically opening parabola is
(x - h)² = 4a(y - k)
where (h,k) are the coordinates of the vertex and a is the distance from the vertex to the focus.
here (h, k) = (2, - 1) and a = 4, hence
(x - 2)² = 16(x + 1) → D
