We also learned what domian and range are along the coordinate plain. The domain lies along the x axis and the range along the y axis. In the early portion of chapter 1, we learned about independent and dependent variables. For each independent variables there is one dependent varibles. We also learned about sequences, which is a function whose domain is a set of natural numbers.
Sequences can be writtin explicitly or recursively.
Lesson 1-1 was a basic review of algebraic terms. In general, it was challenging, but not impossible. Chapter 1 is about the language of algebra, functions notations and graphing functions, Solving equations, rewriting formulas , recursive formulas for sequences, and notation for recursive formulas. I also learned about what a function is. This taught me what an inmdependent and dependent variable is.
