Concept explainers
a.
Find unit length intervals when polynomial function is zero.
a.
Answer to Problem 90E
Explanation of Solution
Given information:
Use the Intermediate Value Theorem, and the table feature of a graphing utility.
Calculation:
Consider the function,
Find the zeros of polynomial using table features by using method,
Enter the function after pressing the key
For table, press the key
Adjust the table to show the zeros of function.
Display shows that the values are changing from negative to positive in the interval
Display shows that the values are changing from positive to negative in the interval
Hence, unit length intervals are
b.
Approximate the zeros of function to nearest thousand.
b.
Answer to Problem 90E
Explanation of Solution
Given information:
Calculation:
Consider the function,
Verify the result using ZERO features is as follows,
Press
Move arrow keys then press ENTER for selecting left-right bounds, zeros will appear on display.
From display zeros obtained are
Hence, zero’s lies on the graph
