State
Evaluating a function answers "what output does this input give"; solving f(x) = k answers "what inputs give this output" — the two questions run in opposite directions.
Show
For f(x) = 2x + 3: evaluating at 5 gives 13; solving f(x) = 13 recovers x = 5.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
