Domain and Range of Composite Functions (Challenging example!)

This video focuses on how to find the domain and range of a composite function. I show students how to find the domain and range of sin(arctanx). In particular, I show students how to organize their work so that they can be accurate and understand the concept of composite functions.

This was so so helpful! I've been having so much trouble with this topic, so it's amazing to finally find a resource that explains it thoroughly with a challenging example. Thank you so much :)
