B.O.B. - Progress in the course

School started about one month ago and so did Precalc Functions. We started with the basics of functions, such as finding the domain and range of linear functions. Then it got more difficult to find the domain and range of radical functions. After this something completely new started, to make composing functions and finding their inequalities. First I didn't understand anything with composing functions, but then I reread the theory paper and could ask Olivia for help and after I have solved some problems I understood what the theory paper was talking about and now I understand how to compose functions and how to find their inequalities.
