Study Guide Overview
This study guide covers functions, including their domain and range, independent and dependent variables, and different representations (graphical, numerical, analytical, verbal). It also explains increasing and decreasing functions, concavity (up and down), and finding zeros/roots of functions. Practice questions and an answer key are provided.

#1.1 Change in Tandem
#A Quick Refresher on Functions
Okay, let's talk functions—not the party kind, but the mathematical kind! 🥧
A function is a relationship where each input (from the domain) has exactly one output (in the range).
Think of it like a machine: you put something in, and you get something specific out. No surprises! 🎁

#Variables
- Independent Variable: The input that you control or change (the cause). 👍
- Dependent Variable: The output that depends on the input (the effect).
