To verify the upper and lower bounds using synthetic division and to determine the real zeros of the function
Upper bound:
Lower bound:

Answer to Problem 76E
Explanation of Solution
Given:
Function:
Upper bound:
Lower bound:
Calculation:
1. Verifying upper bound:
Using synthetic division,
Here, the last row values are positive values or zeros.
Hence, the upper bound of given function is x = 3.
2. Verifying lower bound:
Using synthetic division,
Here, the last row values are alternatively positive and negative.
Hence, the lower bound of given function is x = -4.
3. Calculation of real zeros:
Here, the zeros are calculated using graphical method.
Calculation for graph:
Consider
Values of x | Values of f (x) |
0 | 3 |
1 | -3 |
-1 | 19 |
2 | 13 |
-2 | 51 |
By taking different values of x, the graph can be plotted.
Graph:
Interpretation:
By observing graph, it is clear that the curve of the function meets x-axis at
Hence, the zeros of the function are
Conclusion:
Therefore, the zeros of given polynomial function are
