Understanding how the degrees of polynomials in rational functions affect their asymptotes can be tricky, but let's break it down.

Vertical Asymptotes

Vertical asymptotes happen when the bottom part of a fraction (the denominator) is zero.

This is really important because:

• The degree, or the highest power of the polynomial in the denominator, helps us find where these zeros are.
• Finding these zeros can be hard and might involve tedious steps like factoring or using numbers to solve it.

Horizontal Asymptotes

Horizontal asymptotes are determined by looking at the degrees of the top part (the numerator) and the bottom part (the denominator). Here’s how it works:

• If the degree of the numerator (let's call it $n$) is less than the degree of the denominator (let's call that $m$), the horizontal asymptote is $y = 0$.

• If $n$ is equal to $m$, then the asymptote is given by $y = \frac{a}{b}$ where $a$ and $b$ are the leading coefficients of the numerator and denominator, respectively.

• If $n$ is greater than $m$, the function will go toward infinity, making it harder to predict what will happen.

Making It Easier to Understand

With some practice and by using tools like graphing, these ideas can become clearer. Visualizing rational functions and their asymptotes will help you understand them much better!
