Composing Two Functions Then Determining the Domain in Interval Notation

The video tutorial covers the concept of function composition, specifically G of F of X, and emphasizes the importance of understanding different notations. The teacher checks off a summer packet assignment and discusses the domain of the function, highlighting the restrictions on values that can be used.

The tutorial concludes with a summary of the domain values that work and those that do not.
