Understanding Limits and Asymptotes

The video tutorial discusses the manipulation of functions for clarity, focusing on rewriting functions to make them more visually appealing. It highlights the differences between exponential functions and polynomials, emphasizing that pre-calculus rules for polynomials do not apply to exponential functions. The tutorial explores horizontal asymptotes, examining limits as x approaches both positive and negative infinity. It compares numerical and algebraic approaches to solving these problems, suggesting that different methods may be preferred by different educators.

What is the first step suggested for simplifying the given function?

• Reversing the order of terms in the numerator
