Every page in this folder names an idea you first met messily — at the boards, in a visibly random group, marker in hand. That order is deliberate: the wrestling builds the understanding, and these pages consolidate it, written for your future forgetful self. Read them after the exploration, never instead of it.
Unit 1 — Functions and transformations
- What Is a Function
- Function Notation
- Domain and Range
- Transformations of Functions
- The Inverse of a Function
- Quadratic Functions Revisited
- Equivalent Algebraic Expressions
Unit 2 — Exponential functions
Unit 3 — Trigonometric functions
Unit 4 — Discrete functions and your financial future
Most pages end by pointing at the practice set that turns the idea into a reflex, and at the curriculum expectations the page serves — so you can always see where you are and why we are here.
