In finite difference calculus, which of the following correctly defines the factorial notation of a function x(n) with interval of differencing h?
- 1None of these
- 2x(n) = (x - h)n
- 3x(n) = x(x + h)(x + 2h)...(x + (n - 1)h)
- 4x(n) = x(x - h)(x - 2h)...(x - (n - 1)h)✓
Correct answer
x(n) = x(x - h)(x - 2h)...(x - (n - 1)h)
