To determine the degree of the polynomial based on the given successive results (24, 0, -24, 0, 144, 504), we can analyze the pattern in the outputs.
1. The sequence alternates between non-zero and zero values, indicating that there may be roots at certain points. Specifically, there are two zeros in the list.
2. Let's denote the outputs by \( f(x) \) where each value corresponds to a specific input (let's say consecutive integer inputs).
The values:
- \( f(0) = 24 \)
- \( f(1) = 0 \)
- \( f(2) = -24 \)
- \( f(3) = 0 \)
- \( f(4) = 144 \)
- \( f(5) = 504 \)
3. Since \( f(1) = 0 \) and \( f(3) = 0 \), we know there are at least two roots, specifically \( x = 1 \) and \( x = 3 \).
4. A polynomial with \( n \) roots can be at most degree \( n \) if counted with multiplicity. Therefore, the polynomial can have a minimum degree of 2 because we already have two roots. However, we need to check if the output values suggest a higher degree polynomial.
5. Looking at the pattern again, we need to create some differences to see how quickly the values change. The outputs can be analyzed by finite differences or other methods, but with 6 distinct outputs, we can infer that the degree might be equal to the number of outputs minus 1, which would suggest a polynomial degree of \( 5 \).
Therefore, given the information and analysis, the degree of the polynomial is likely:
**d. 5**
