State
The zero of a linear function is the input where the output is 0, found by solving f(x) = 0; a nonconstant linear function has exactly one.
Show
A profit model P(x) = 3x − 6 zeroes at x = 2 — the break-even point, where losses hand off to gains.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
