Math Problem Statement
solve the immage
What is the horizontal asymptote of the graph of \(f(x) = \frac{x+1}{x^2-3x-4}\)?
Solution
To solve for the horizontal asymptote of the given rational function:
Steps to Solve:
- Degree of numerator: The numerator is a polynomial of degree 1.
- Degree of denominator: The denominator is a polynomial of degree 2.
Rule for Horizontal Asymptotes:
- When the degree of the denominator is greater than the degree of the numerator, the horizontal asymptote is:
Final Answer:
Additional Questions for Practice:
- What are the vertical asymptotes of the function ?
- How do you find the horizontal asymptote if the degrees of the numerator and denominator are equal?
- What happens if the degree of the numerator is greater than the denominator in a rational function?
- Factorize to find its roots.
- Can a rational function have both horizontal and oblique asymptotes? Explain.
Tip:
For horizontal asymptotes:
- Compare the degrees of the numerator and denominator polynomials.
