Polynomial interpolation is an interpolation that based on three value points (two previous points and next point). So, if we see the data, there are an ID 1, 4, and 8. So, we need to find out the value of 2, 3, 5, 6, and 7 based on value 1, 4, and 8. The formula is that
(((x-x2) * (x-x3)) / ((x1-x2) * (x1-x3))) * y1 + (((x-x1) * (x-x3)) / ((x2-x1) * (x2-x3))) * y2 + (((x-x1) * (x-x2)) / ((x3-x1) * (x3-x1))) * y3
x = current ID;
x1 = the first known ID (second previous known ID); ---> 1
x2 = the second known ID (first previous known ID); ---> 4
x3 = the third known ID (next known ID); ---> 8
y1 = the first known value (the value of ID x1)
y2 = the second known value (the value of ID x2)
y3 = the third known value (the value of ID x3)
