Limits at Infinity: Composition of Functions and Continuity

This lecture covers the composition of functions, composition and continuity, infinite limits, and limits at infinity. It explains the concept of continuity at a point, the behavior of functions near infinity, and the conditions for functions to be continuous. The lecture also delves into examples illustrating the application of these concepts in algebra and limits. The instructor emphasizes the importance of understanding the behavior of functions as they approach infinity and the implications for the continuity of functions.
