Creating Sliders to Examine Exponential Functions

 

Sliders are gadgets in Geogebra (or any similar software) that allow you to change the value of a variable in an equation without having to change the variable by hand multiple times.  You simply "slide" the button and the value of the variable changes as does the corresponding graph. 

 

 

Creating sliders is rather easy.  Just follow the set of steps below and you'll be graphing exponential functions in no time.

 

1.  Open Geogebra and select the slider button. 

 

2.  Click anywhere on the graph section of Geogebra.  You can move the slider    

     later if it is in the way.  You can name the slider anything you want, but in

     this case, name it "b" and select Apply.

  • If the preset Interval in the slider does not provide the values you need, simply right click on the slider at any time and select "Object Properties" to change the Interval values.

​3.  Now type an exponential function into the input bar in the form y=b^x.

4.  You can now use the slider to change the value of the base.  It is important    

     to remember that you must select the "Move" icon to change the value  

     of the slider.

5.  Now continue the exercise using the Graphing Exponential Functions OneNote and add additional sliders as indicated.
