Sagot :

To find the degree of the polynomial that produces the given successive results, we analyze the sequence of differences until we find a constant difference. Here are the successive results: 24, 0, -24, 0, 144, 504.

Let's go through the steps to find the differences:

1. First differences:
[tex]\[ 0 - 24 = -24 \][/tex]
[tex]\[ -24 - 0 = -24 \][/tex]
[tex]\[ 0 - (-24) = 24 \][/tex]
[tex]\[ 144 - 0 = 144 \][/tex]
[tex]\[ 504 - 144 = 360 \][/tex]
So, the first differences are: -24, -24, 24, 144, 360.

2. Second differences:
[tex]\[ -24 - (-24) = 0 \][/tex]
[tex]\[ 24 - (-24) = 48 \][/tex]
[tex]\[ 144 - 24 = 120 \][/tex]
[tex]\[ 360 - 144 = 216 \][/tex]
So, the second differences are: 0, 48, 120, 216.

3. Third differences:
[tex]\[ 48 - 0 = 48 \][/tex]
[tex]\[ 120 - 48 = 72 \][/tex]
[tex]\[ 216 - 120 = 96 \][/tex]
So, the third differences are: 48, 72, 96.

4. Fourth differences:
[tex]\[ 72 - 48 = 24 \][/tex]
[tex]\[ 96 - 72 = 24 \][/tex]
So, the fourth differences are: 24, 24, which is constant.

Since it took four levels of differences to reach a constant difference, the degree of the polynomial is 4.

Therefore, the correct answer is:
c) 4
