Math Problem Statement
Solution
The function in the image is .
Here are the steps to solve each part:
a. Horizontal Asymptote(s)
To find the horizontal asymptote(s), we analyze the behavior of the function as and .
- Degree of the numerator: The numerator has degree 2 (the highest power of is ).
- Degree of the denominator: The denominator also has degree 2 (the highest power of is ).
When the degrees of the numerator and denominator are equal, the horizontal asymptote is given by the ratio of the leading coefficients of the highest degree terms.
The leading coefficient of the numerator is 2, and the leading coefficient of the denominator is 1. Therefore, the horizontal asymptote is:
b. Right-hand side and left-hand side limits as
We now examine the limits of the function as approaches 2 from both sides:
- Right-hand limit: As , the denominator approaches 0 from the positive side because is positive but small.
- Left-hand limit: As , the denominator approaches 0 from the negative side because is negative but small.
In both cases, since the numerator remains finite, the limits approach infinity but with opposite signs:
So there is a vertical asymptote at .
