How to Find Inflection Points in GeoGebra
You can use GeoGebra to find the inflection points of a function, and the tangent at a given inflection point:
GeoGebra Instruction 1
- 1.
- Open
Algebra ViewandGraphics Viewunder
Viewin
Menu. - 2.
- Input your function into
Algebra Viewand pressEnter. - 3.
- Type the command
InflectionPoint(<Polynomial>)inAlgebra View. For<Polynomial>, enter the name of your function, then pressEnter. The coordinates of the inflection points will appear inAlgebra View. - 4.
- Click
Tangents
, then the inflection point and the graph. You’ll get a tangent at the inflection point. The equation of the tangent can be found in Algebra View.
Note! GeoGebra will only find the inflection points of polynomial functions.
