Solution 10434: Graphing a Piecewise Function on the TI-85 or TI-86.

How can I graph a piecewise function on the TI-85 or TI-86?

A piecewise function allows specific restrictions to be made when graphing a function. To graph the piecewise f(x)= x, when x > 0 follow the steps listed below.

  • Press [GRAPH] [F1]
  • Input x into y1= using [x-VAR]
  • Press [÷] [(] and input x, using [x-VAR]
  • Press [2nd] [2](TEST)
  • Press [F3], enter 0, and press [)]
  • Press [GRAPH] [F5]
Please see the TI-85 or TI-86 guidebooks for additional information. n field]
