The source highlights FUNCTION; its complete screen is in the evidence.
Fraction alternative: ALPHA → Y=
- FRAC menu: 1:n/d 2:Un/d
- 3: n/d ↔ Un/d 4: F ↔ D
- Select 1:n/d; numerator 1, denominator X gives Y₁ = 1/X.
- Use denominator X² for Y₁ = 1/X².
Teacher guidance: use TI-SmartView to introduce graphing settings.
Menu reconstruction retains source options; the date/clock is not a setting task.
