Asymptotes are really important for understanding polynomial functions. They help us see how the graph behaves as it gets really big or approaches a specific value.

Types of Asymptotes:

1. Horizontal Asymptotes:

   • These show the value the function gets closer to as (x) goes to positive or negative infinity.
   • For example, in the function (f(x) = \frac{2x^2 + 3}{x^2 + 1}), it gets closer to the horizontal asymptote at (y = 2).

2. Vertical Asymptotes:

   • These point out where the function is not defined, which usually happens at certain points in the denominator.
   • For example, in (g(x) = \frac{1}{x - 1}), there's a vertical asymptote at (x = 1).

Why They're Important:

• Predicting End Behavior:

  • Asymptotes help us guess what happens to the graph at the ends, giving us a better overall understanding.

• Graph Sketching:

  • Knowing where the asymptotes are helps us draw the graph more accurately.
  • This is especially useful for seeing where the function goes up really high or levels off.

In short, asymptotes make it easier to analyze polynomial functions!
