(c)
Answer to Problem 35E
The rational solution from graph of
Explanation of Solution
Given information:
The given polynomial function as shown below,
Formula used:
The value of f(x) will be equated to zero.
Calculation:
It is clear the polynomial will have only three solutions because of its degree is three, so the rational solution from graph of
Conclusion:
The rational solution from graph of
