To properly graph all kinds of functions (many of which don’t have a parent function you can easily translate), you need to first find the domain–all x-values at which the functions exist. Some functions don’t exist at a certain point; some don’t exist at a range of points. Arun and Katie describe the domain and how to find it, and present examples of functions with different domains.
