To analyze: the graph of given function
Answer to Problem 43AYU
Explanation of Solution
Given:
Calculation:
STEP 1: Rewrite the function as
The domain of
Since
STEP 2: The function
STEP 3:
STEP 4: Degree of the numerator is greater than the degree of the denominator. So, the rational function is improper. To find any horizontal or oblique asymptote, we use long division.
The quotient is
STEP 5: The numerator has no zero and the denominator has one zero at
Now, construct the table.
Interval Number chosen Value of f Location of graph Point on graph |
Plot the points from the table obtained.
STEP 6: Since the graph of
Also, as the graph will approach the vertical asymptote
STEP 7: The figure shows the final graph.
Conclusion:
Thus, the graph of
