How is a finite difference formula derived from?
Finite difference formulas are derived by interpolating function values, followed by differentiation of the interpolant. We can in principle derive any finite difference formula from the same process: Interpolate the given function values, then differentiate the interpolant exactly. Some results are given here for two important special cases.
How are finite differences related to polynomial degree?
Read that example carefully. Notice that the finite differences method determines only the degree of the polynomial. To find the exact equation for the polynomial function, you need to find the coefficients by solving a system of equations or using some other method.
