The video explores the concept of limits as x approaches infinity, demonstrating that an infinite number of functions can share the same limit. Through graphical examples, it shows how different functions, including those with natural logs and oscillations, approach a limit of three. The video emphasizes that even as x becomes very large, functions can behave differently but still converge to the same limit. The discussion includes zooming in on graphs to analyze function behavior and concludes by reinforcing the idea of infinite functions sharing a common limit.

What is the main goal of the video regarding limits at infinity?

• To explain that limits at infinity are always zero.

• To demonstrate that limits at infinity do not exist.

• To show that an infinite number of functions can have the same limit.

• To prove that only one function can have a specific limit.

What is an asymptote in the context of this video?

• A line that the function never touches but gets infinitely close to.

• A point where the function changes direction.

• A point where the function is undefined.

Why is it important to zoom in on the graph as x becomes very large?

• To see the function diverge.

• To find the function's roots.

• To observe the function's behavior near the asymptote.

• To identify the function's maximum value.
