Solution
The given function is . This is a rational function, and we need to identify and draw the horizontal and vertical asymptotes based on this function.
Horizontal Asymptote:
For rational functions of the form , the horizontal asymptote depends on the degrees of the polynomials and :
- If the degree of is less than the degree of , the horizontal asymptote is .
- If the degrees are equal, the asymptote is .
- If the degree of is greater than , there is no horizontal asymptote.
In this case, , so the degree of the numerator is 0 (since it's a constant), and the degree of the denominator is 1. Thus, the horizontal asymptote is: So, draw a horizontal line at on the graph.
Vertical Asymptote:
The vertical asymptote occurs where the denominator equals zero, which would make the function undefined. Setting the denominator equal to zero: Thus, there is a vertical asymptote at .
Steps for Drawing:
- Horizontal Asymptote: Draw a horizontal line at (along the x-axis).
- Vertical Asymptote: Draw a vertical line at .
This will complete the graph with the correct asymptotes.

Follow-up questions:
- How do you identify vertical asymptotes for any rational function?
- What happens to the graph of as approaches 1?
- Can a rational function have more than one horizontal asymptote?
- How does the behavior near vertical asymptotes affect the overall shape of the graph?
- What is the relationship between the degree of the numerator and denominator in determining horizontal asymptotes?
Tip: When graphing, always consider the behavior of the function as and as to help identify asymptotes.
