Inside Collection (Course): Precalculus with Engineering Applications
Summary: This module provides an introduction to the concept of functions.
The unit on functions is the most important in the Algebra II course, because it provides a crucial transition point. Roughly speaking…
Each step builds on the previous step. Each step expands the ability of mathematics to model behavior and solve problems. And, perhaps most crucially, each step can be frightening to a student. It can be very intimidating for a beginning Algebra student to see an entire page of mathematics that is covered with letters, with almost no numbers to be found!
Unfortunately, many students end up with a very vague idea of what variables are (“That’s when you use letters in math”) and an even more vague understanding of functions (“Those things that look like
The good news is, variables and functions both have very specific meanings that are not difficult to understand.
