OK, smart guy, yes…yes, I have kinda avoided the equals parts of the domain restrictions. SO, WHY ARE YOU AVOIDING “EQUALS” IN YOUR FUNCTIONS? The sharing features are another aspect of Desmos which have improved greatly in the past year. Click the icon below to play with the document online. Then, a can be used in the piecewise function. For mine, I chose to limit the domain to between -10 and 10, and have step counts of. In Desmos, start by defining a slider for the parameter “a”. Consider this problem:įor what value(s) of x is the piecewise function below continuous? Sliders can be used to have students explore the continuity of a piecewise function. So, the piecewise function above would be entered as: And commas are used to have multiple function rules in one command. In the Desmos calculator, colons are used to separate domain restrictions from their functions. Let’s say we want to graph this piecewise function: But I’ll provide a few examples here, and some teaching tips. The Desmos knowledge base provides instructions for graphing a piecewise function, and a neat video tutorial. #PIECEWISE FUNCTION CALCULATOR HOW TO#
