Answer:
The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:
Step-by-step explanation:
Given the table
x y
0 3
1 4
2 7
3 12
The (first) difference, let suppose denoted by d, of y values can be obtained by taking the difference between consecutive terms.
The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:
