To find: Intercepts and asymptotes of the given function as well as plot graph.
Answer to Problem 16CT
There are no x-intercepts and no y-intercepts.
There are no horizontal asymptotes of the graph of the function
The vertically asymptotes of function is
Explanation of Solution
Given:
The function:
Consider the following function
To find the x-intercepts put
Since the above equation has no real roots, therefore there are no x-intercepts
To find the y-intercept, put
Thus, the function has no y-intercepts.
From the above function, note that as x tends to infinity, the function also approaches to infinity
Thus, there are no horizontal asymptotes of the graph of the function
To find the vertically asymptotes, put the denominator of the function to zero and solve for x
Thus, the vertically asymptotes of function is
Consider the table
Test interval | x | y | Sign | Point of graph |
−3 |
| Negative | ||
2 | 6 | Positive | (2,6) | |
3 | Positive |
Thus, the graph of the function is shown below
