(a)
The possible list of the rational zeros of f.
(a)
Answer to Problem 33E
The possible rational zeros is
Explanation of Solution
Given information:
The given polynomial function as shown below,
Formula used:
f (x) = 0 using the Rational Zero Test.
Calculation:
To find the values of x for which f (x) = 0 using the Rational Zero Test.
The leading coefficient is 1and the constant term is -4.
Possible rational zeros:
Conclusion:
The possible rational zeros is
(b)
The graph of the function f.
(b)
Answer to Problem 33E
The graph increases and decreases monotonically.
Explanation of Solution
Given information:
The given polynomial function as shown below,
Formula used:
The horizontal axis represents x −axis and the vertical axis represents the y-axis.
Calculation:
Now draw the graph of f (x) it shown below:
Conclusion:
The graph increases and decreases monotonically.
(c)
The real zeros of f.
(c)
Answer to Problem 33E
The value of f (x) is
Explanation of Solution
Given information:
The given polynomial function as shown below,
Formula used:
The f(x) is 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 f (x) are
Conclusion:
The value of f (x) is
