A piecewise function is actually made up of "pieces" of different functions. Each function "piece" is defined over a certain interval. Using your TI-84 Plus calculator to graph piecewise functions can be a bit tricky, but you'll get the hang of it soon enough.. The TI-84 Plus is a graphing calculator that can be used for many math purposes. This post will go over how to use the TI-84 Plus in order to graph piecewise functions. Piecewise functions are mathematical equations with two or more sets of conditions.
How to enter the fcn, prepping the graphing window, graphing the fcn, fixing the problems with the graph, and a 2nd method to graph a piecewise fcn.Buy the T.. To work around this limitation place each piecewise function in a seperate line, for example place the first in Y1 and the second in Y2 etc. Please see the TI-83 Plus, TI-84 Plus, and TI-84 Plus C Silver Edition guidebooks for additional information.
