Description

Systems with Nonlinear Functions — Function Notation Formalized is Unit 4 of Algebra I (Grade 9), the Letters & Devotion Math course, complete in one printable PDF: 8 lessons, the unit check-up and the answer key, 63 pages.

• Function notation f(x) as input-output correspondence
• Comparison of function properties across representations
• The equivalence between graphical intersection and algebraic solution of f(x)=g(x)
• Graphical solution of f(x)=g(x) for a linear-nonlinear pair
• Number of solutions to f(x)=g(x) as a property of the specific function pair
• Translation of a verbal scenario into a function pair and interpretation of their intersection
• The general equivalence of graphical and numerical solution methods for f(x)=g(x)
• The meaning of the notation f(x) versus multiplication notation

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
