Write Polynomial Functions and Models

2. Use finite differences and a system of equations to find a polynomial function that fits the data in the table.
Step 1: Use finite differences to find the degree of the polynomial.
Step 2: Set up a system of equations and solve for the missing variables.
Step 3: Solve the system of equations and write a polynomial function.
