Domain and Range of Functions

The video explores the domain and range of various parent functions, including absolute value, rational, exponential, and logarithmic functions. It explains how to express these in set and interval notation, emphasizing the importance of understanding which values are permissible for x (domain) and y (range). The video concludes with an invitation to explore further resources for deeper understanding.
