Answer:
This question needs rephrasing. It makes no sense.
Step-by-step explanation:
The equation of parabola is 
Comparing with the vertex form of the parabola: 

Hence, the vertex of the parabola is given by (h,k) = (1, -2)
Now, vertex is the midpoint of the focus and the point on the directrix.
Distance, between vertex and focus is p and that of point on the directrix is p.
Now, let us find p

Thus, the focus is given by

And the directrix is given by

Since, a >0 hence, it is an upward parabola.
The graph is shown in the attached file.
