Math Problem Statement
Solution
From the image provided, the function is given as:
Steps to Analyze and Solve:
1. Determine Vertical Asymptotes:
Vertical asymptotes occur when the denominator equals zero. Solve: Thus, the vertical asymptote is at .
2. Check for Holes:
Holes occur when there is a common factor in the numerator and denominator, which cancels out. In this case, there is no such factor, so there are no holes.
3. Find the Horizontal Asymptote:
The degrees of the numerator () and the denominator () are different. Since , there is no horizontal asymptote. Instead, we look for an oblique asymptote.
4. Determine the Oblique Asymptote:
Perform polynomial long division: Divide by to get . Multiply and subtract, and continue until you reach the remainder. The oblique asymptote is given by the quotient:
5. Domain and Range:
- The domain is all real numbers except where the denominator is zero: .
- The range is all real numbers except at , as approaches this line asymptotically.
6. Determine if the Graph Crosses the Horizontal/Oblique Asymptote:
To test if it crosses the oblique asymptote, set and solve for . Substituting this back into reveals if there are solutions.
Would you like me to calculate points for plotting or solve specific parts further? Here are a few questions to deepen your understanding:
- How does the oblique asymptote affect the behavior of the graph for large values of ?
- Can you confirm the behavior of near ?
- Would you like detailed steps for the long division used to find the oblique asymptote?
- Do you need the graph plotted with specific points?
- Would you like help completing the table of values for better visualization?
Tip: For functions with higher-degree numerators, always check for oblique or other asymptotes carefully!
