First Derivative Test
The map in words
- Critical point c
- Test f' just LEFT of c
- f' left = ?
- Positive (+): +
- Combined
- + then -: LOCAL MAX
- - then +: LOCAL MIN
- same sign: INFLECTION
- Combined
- Negative (-): -
- Positive (+): +
- f' left = ?
- Test f' just RIGHT of c
- f' right = ?
- Positive (+): +
- Negative (-): -
- f' right = ?
- Test f' just LEFT of c
Summary of Tests — Comparison
