1. Reflect on what the graphs are suggesting for one equation, two equations, and three equations, and describe your observations. Think about the equation as a functionofxandy, for example,in the example above. Geogebra automatically interprets this way, that is, like, it isolateszin the equation.

2. What did the graphs show when you entered the second equation?

3. Give a simple description of the system

x=0 y=0 z=0

x= 0 can be seen as the constant function. Of course, you can use GeoGebra to "observe" the system.

4. Give an example with 2 equations as simple as possible with 3 variables (at least 1 being non-linear; keeping z to the one power on both equations) and describe the potential ofGeoGebrato study nonlinear systems.
