I can determine the domain of a composite function by using the restrictions of the two parent functions.
Composite Functions & Their Domains – Ch. 1 (page 121-125)
Domain & Range of Composite Functions Worksheet – Ch. 1 (page 113)
I can determine if a function is unbounded; bounded above, bounded below, or bounded above & below; or bounded on its own domain by using its graph.
