Answer:

4th degree

Step-by-step explanation:

We can use a technique called finite differences.

In column 1  put the differences  between the y values  (y2-y1)

Keep adding columns with the differences until they become constant.

Column 2 is column1 differences  (-2- -30) etc

Column3 is column 2 differences

Column 4 is column3 differences

The differences in column4 are the same, so we can stop

This will be a 4th degree polynomial

x    y          column 1               column 2      column 3        column 4

-2  30        

-1   0                 -30                    

0   -2               -2                           28

1      0               2                           4               -24

2     30           30                          28               24              48

3    160           130                        100               72               48

4      510        350                       220               120             48
