FN6 Question

[tdegeorge]

FN6 focuses on inverses and some activities suggest students to "confirm" two functions are inverses by doing composition. But right now, there is no remark or definition about how compositions can help determine if two functions are inverses. Should we add a remark or something somewhere about that? @kathypinzon @AbbyANoble

[kathypinzon]

yeah, we need a remark that says something like
Two functions are inverses if f(g(x))=x......
or maybe we need an activity to discover it.

Isn't that Definition 2.6.4 ?
