(a)
Answer to Problem 36E
The possible rational zeroes are
Explanation of Solution
Given information:
The given function as shown below,
Formula used:
Calculation:
The Rational Zero Test
If the polynomial
Where,
Here,
Use the above rational zero test, therefore the possible rational zeroes are
Conclusion:
The possible rational zeroes are
(b)
The graph of f.
(b)
Answer to Problem 36E
The zeroes of the function f(x) lies between -1 and 3
Explanation of Solution
Given information:
The given function as shown below,
Formula used:
The graph is plotted against the x-axis and y-axis.
Calculation:
The graph of the function
From the above graph, note that the zeroes of the function f(x) lies between -1 and 3
Conclusion:
The zeroes of the function f(x) lies between -1 and 3
(c)
The zeros of f.
(c)
Answer to Problem 36E
The real zeroes of the function
Explanation of Solution
Given information:
The given function as shown below,
Formula used:
The function value is equated to zero.
Calculation:
Put x =1 in the above function
Therefore,
Take
Therefore, the above polynomial can be written as
Thus, the real zeroes of the function
Conclusion:
The real zeroes of the function
