State
Function composition feeds one function's output into another as input: (f ∘ g)(x) = f(g(x)), reading inside out.
Show
For f(x) = x² and g(x) = x + 1: f(g(2)) runs g first — g(2) = 3 — then f: f(3) = 9. Two machines, one assembly line.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
