If your amount of fencing was 247.10 then you would divide that by 4 and multiply your result by 36 to find the amount of money needed to build a fence, your result is $2,196, now of course you have have more than 4 feet left but since the problem asks every 4 feet of fencing costs $36, I’m going to assume that if you have more than 4 but less than 8 you get that for free
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.
