(a)
To Find: The degree, leading coefficient and the end behaviour.
(a)

Answer to Problem 46PPS
The degree is 1, the leading coefficient is 1 and the end behaviour is that both ends go up.
Explanation of Solution
Given:
The given function is
Calculation:
From the given function the degree is 4 as it is highest power of the function.
The leading coefficient 1 as it is the coefficient of the variable of the highest degree.
Consider the end behaviours as it is even degree polynomial and the leading coefficient is positive so the ends that will both go up.
(b)
To Find:The table of the integer values
(b)

Answer to Problem 46PPS
Therequired table for the 10 zeroes is shown in Table 1
Explanation of Solution
Consider the given function is,
The table to the integer values
Table 1
-4 | 1414.224 |
-3 | 690.5655 |
-2 | 287.287 |
-1 | 92.4885 |
0 | 18.27 |
1 | 0.7315 |
2 | -0.027 |
3 | 0.0945 |
4 | 9.916 |
The above table shows two change of signs and the number of zeroes.
Thus, the required table for the 10 zeroes is shown in Table 1
