Concept explainers
To identify: The symmetry with respect to x -axis, y -axis, and the origin and x -intercept (s) of polynomial function
Answer to Problem 101E
The function
Explanation of Solution
Given data:
The given polynomial function
Method/ concept used:
The graph of the function is plotted using graphing calculator. The x -intercept of the function
Graph:
The graph of the polynomial function
Interpretation of the Graph:
Since the graph of
[Note: if replacing y by - y function does not change then the function is symmetrical about x − axis, e.g.,
Since the graph of
[Note: if replacing xby - x function does not change then the function is symmetrical about y - axis, e.g.,
Since the graph of
[Note: A function is said to be symmetric with respect to the origin if
Thus, the function
The graph of
Conclusion:
The function
