Today Joshua and I met on Teams. We completed the notes for 2.7B and started 2.8. We covered further the concept of composing functions by substituting one function into the other. Today we considered how that would affect its domain. We discussed what would make a function have restrictions (negative radicals, undefined). We practiced composing the functions and then identifiying their domain. Joshua seemed to pick up on this concept easily, as it is a review from Algebra 2.
