Find the zeros of the function

Answer to Problem 26E
Explanation of Solution
Given:
Function:
Calculation:
To find the roots of given function, put
Now, writing the given function as product of linear factors,
Calculation for graph:
Consider
Values of y | Values of f (y) |
0 | -625 |
1 | -544 |
-1 | -544 |
2 | 671 |
-2 | 671 |
By taking different values of y, the graph can be plotted.
Graph:
Interpretation:
Only real zeros of the function can be verified through graph.
By observing graph, it is clear that the curve of the function meets x-axis at
Hence, the real zeros of the function are
Conclusion:
Therefore, the zeros of given function are
