What Makes a Function?

A function is a special relationship where each input (x-value) has exactly one output (y-value). The vertical line test helps us check this!

📊 The Vertical Line Test

If any vertical line crosses a graph more than once, it's not a function.

Key Rule: One input → One output

🎯 Domain & Range

Domain: All possible x-values
Range: All possible y-values

Example: f(x) = x²
Domain: (-∞, ∞)
Range: [0, ∞)

📈 Function Behavior

Increasing: Going up ↗
Decreasing: Going down ↘
Constant: Staying flat →
Concave Up: Holds water ∪
Concave Down: Sheds water ∩
