Answer to Problem 30E
Upper bound: 5
Lower bound:
Explanation of Solution
Given information:
Calculation:
r | 1 -3 -2 3 -5 | |
1 | 1 -2 -4 -1 | - 6 |
5 | 1 2 8 43 | 210 |
Since
Then
r | -1 3 -2 -3 -5 | |
1 | -1 2 0 -3 | - 8 |
5 | -1 -2 -12 -63 | -320 |
Since 5 produces no changes in sign in
Then
Upper bound: 5
Lower bound:
