Concept explainers
a.
To use the zero or root feature of a graphing utility to approximate (accurate to the nearest thousands) the zeros of the function.
a.
Answer to Problem 102E
Explanation of Solution
Given: Given function is
Concept Used:
Zeros are the values for x for which function gives zero value.
Calculation: To graph the function calculates the following points of the graph.
s | f(s) |
0.764 | 0 |
2.5 | 16.625 |
5.236 | 0 |
5.5 | -0.625 |
6 | 0 |
Graph the function on the above points
Where x- axis represents s and y -axis represents f(s).
b.
To find one of the exact zeros and use synthetic division to verify result.
b.
Answer to Problem 102E
s =6 an exact zero of the given polynomial function.
Explanation of Solution
Given: Given function is
Concept Used:
Synthetic division is used here.
Calculation:
s= 6 looks like an exact zero. Confirm with synthetic division.
Using the bottom row as coefficient of the resulting polynomial from dividing f by (s -6).
