First of all, find a program or a calculator that will give you the answer. Then you'll know how to make your table. I recommend Desmos. I have inserted the final graph for you.
Make up a table for this graph. Put the lowest point as the central entry in your graph.
x y
-4
-3
-2
-1
0
Now fill in the y values.
x y
-4 1
-3 -3.5
-2 -5
-1 -3.5
0 1
You can use the outline of the parabola and then mark the outline with the points in the table.

Answer:
There are
rows in the theater.
Step-by-step explanation:
Given terms.
Seats in order
will form an Arithmetic progression.
As the common difference
,same for three consecutive terms so this an AP.
Now accordingly we can put the AP terms.
Total number of seats 
Seats in the first row 
Seats in the last row 
Summation of
terms in AP
![S_n={\frac{n}{2}[2a+(n-1)d]}](https://tex.z-dn.net/?f=S_n%3D%7B%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%7D)
OR
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
Using the second equation.
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
![1560=\frac{n}{2}[23+81]](https://tex.z-dn.net/?f=1560%3D%5Cfrac%7Bn%7D%7B2%7D%5B23%2B81%5D)

So the number of rows (n) in the theater
