To find the least integral upper bound and greatest integral lower bound for the roots of the equations.
Answer to Problem 30WE
Lower bound
Explanation of Solution
Given information:
The given equation is
Calculation :
For upper bound,
There are no roots above 3.
There is a root between 2 and 3, so 3 is the least integral upper bound of the roots.
For lower bound,
There are no roots for
There is root between
Therefore,
Lower bound
