Instructional Ideas

• Have learners find the domain of the given function on their own before watching video

Classroom Considerations

• Pupils must have knowledge of continuity and of domains
• Note that the video refers to third roots; individuals should know that this is the same as cube roots

• This video is hosted on YouTube

Pros

• Shows graph to confirm results

Cons

• Focuses solely on cube root functions and does not consider other types of functions
