GeoGebra Tutorial 32 – Graphing Piecewise Functions

In this tutorial, we are going to learn how to graph piecewise functions. In our example, we will graph the piecewise function

f(x) = \begin{cases} 1-x, x \leq 1 \\x^2, x > 1 \end{cases}.

The output of our tutorial is shown below.  GeoGebra has not yet developed a way to construct piecewise functions, however, its features is more than good enough for improvisation. In the construction below, we will use the function command to graph functions with specified domains. We will create manually, the two endpoints of the functions on (1,1) and (1,0). We will also use the vector tool to construct arrows.
