Direction parabola opens upward.

Vertex of parabola is (27,-9).

Axis of symmetry is .

Step-by-step explanation:

Note: Option sets are not correct.  

The vertex form of a parabola is

   ...(1)

where, (h,k) is vertex and x=h is the axis of symmetry.

If a<0, then parabola opens downward and if a>0, then parabola opens upward.

The given function is

    ...(2)

On comparing (1) and (2), we get

, so direction parabola opens upward.

, so vertex of parabola is (27,-9).

So, axis of symmetry is .
