Determine domain and range and if a relation is a function

The video tutorial explains how to determine the domain and range from a set of ordered pairs and assess whether the set represents a function. It begins by defining ordered pairs and their components, then moves on to identifying the domain and range. Finally, it explains how to determine if the set is a function by checking if each domain element corresponds to exactly one range element.
