Would enjoy your input!Īnd finally, I started this post by sharing some of the search terms which cause people to find my blog. But my early impression is that it is a addition which works seamlessly with the existing, awesome, calculator.Īlso, while I’m in a sharing mood, here is a quick file I created to use in an absolute value inequality unit. The Desmos folks tend to monitor these things, so let’s see if they have a suggestion here.ĭown the road, I want to take a deeper look at the new table feature, and will report out. Let’s graph this function:Ĭlick this link to find out what happened when I tried to enter this function on Desmos. Something neat (odd, goofy) happens when an equals is used in the domain restrictions. Title: Worksheet Piecewise Functions Author: Shai McGowan Created Date: 5:47:53 PM. Match the piecewise function with its graph. OK, smart guy, yes…yes, I have kinda avoided the equals parts of the domain restrictions. Then, find the domain and range for each piecewise function. 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.
