Exploring Adding and Subtracting Rational Expressions

The video tutorial covers the comparison between quadratic and exponential functions, emphasizing that exponential functions eventually grow faster. It includes a warm-up activity to order expressions, an activity to compare growth patterns, and a detailed analysis of growth steps. Equations for both patterns are derived, and growth factors are compared to illustrate why exponential functions surpass quadratics over time. The session concludes with a cool down activity.

Which function type grows faster over time?
