Concept explainers
a.
Identify the function shown in the graph.
a.
Answer to Problem 131E
It is not the correct function.
Explanation of Solution
Given information:
The graph of one of the following functions is shown below. Identify the function shown in the graph. Explain why each of the others is not the correct function. Use a graphing utility to verify your result.
Calculation:
Consider the graph,
As per the graph the zeros are (the line of intersection on
Now find the zeros of the function by equating
So the zeros of the given function are not same as graph functions, it is not the correct function.
Hence, it is not the correct function.
b.
Identify the function shown in the graph.
b.
Answer to Problem 131E
It is not the correct function.
Explanation of Solution
Given information:
The graph of one of the following functions is shown below. Identify the function shown in the graph. Explain why each of the others is not the correct function. Use a graphing utility to verify your result.
Calculation:
Consider the graph,
As per the graph the zeros are (the line of intersection on
Now find the zeros of the function by equating
So the zeros of the given function are same as graph functions but there is no imaginary root, it is not the correct function.
Hence, it is not the correct function.
c.
Identify the function shown in the graph.
c.
Answer to Problem 131E
It is the correct function.
Explanation of Solution
Given information:
The graph of one of the following functions is shown below. Identify the function shown in the graph. Explain why each of the others is not the correct function. Use a graphing utility to verify your result.
Calculation:
Consider the graph,
As per the graph the zeros are (the line of intersection on
Now find the zeros of the function by equating
So the zeros of the given function are same as graph functions having imaginary root, it is the correct function.
Now Use a graphing utility to verify your result.
Use
Press
Now click on the GRAPH button to display the graph.
Hence both the graphs are matched so result is verified.
Hence, it is the correct function.
d.
Identify the function shown in the graph.
d.
