In this quick and fun math video, we take a set of coordinate points and turn them into a T-chart (table), plot them on a graph, and figure out the domain and range. Then we finish by asking the big question: Is this a function? If you've ever been unsure how to read a relation or check if it’s a function, this example will clear it up fast. Plus, there’s a neat math trick to remember what to repeat (and what not to) when listing your domain and range. Grab a pencil and follow along!
