Hello All About Circuits fellows,

May I know if there is an online calculator or a software that would graph a piecewise function? I do not have a TI-83 calculator or similar.

Thank you very much.

 

You can always build it up in Excel (or any other spreadsheet).

 

LibreOffice has a spreadsheet application like Excel and it's free
Scilab is similar to Matlab and it's free
R is a package used by statisticians and it's free

Running down those three software packages should keep you off the streets for a while. They are all very capable packages for plotting and other things.

 

Try desmos. I am using it as a Chrome plugin (free). Easy to use and very capable.

Here is an example of a piecewise function. Notice the constrain on X in each of the pieces.

You can turn each of the pieces on/off by clicking on the left hand icons.
