GeoGebra
You can use CAS and Algebra View to work with rational functions, and find asymptotes or the values of the function.
You can plot rational functions in Graphics View in the same way as all other functions.
GeoGebra has its own command for asymptotes: Asymptote(<Object>).
GeoGebra Instruction 1
Asymptotes in CAS
- 1.
- Open
CASunder
Viewin
Menu. - 2.
- Start typing
Asymptote(<Object>)inCAS. Replace<Object>with the name of your function or expression and pressEnter. - 3.
- The solution given is of the form
where is a horizontal or the oblique asymptote, and is a vertical asymptote.
GeoGebra Instruction 2
Asymptotes in Graphics View
- 1.
- Open
Algebra ViewandGraphics Viewunder Viewin Menu. - 2.
- Type your function into
Algebra Viewand pressEnter. The function is then saved inAlgebra View. - 3.
- Use the command
Asymptote(<Object>)and replace<Object>with the name of your function. The asymptotes will then appear inGraphics View.
