This page supports the Reduce the Dimension activity from the Cartesian Connections unit.
Examples of all four geometric functions have been restricted to Lineland, so that the independent and the dependent variables both stay on Lineland.
Your job is to figure out which ones can be messed up and which ones can't.
To mess up a function, just change it (by changing the mirror, the vector, the angle of rotation, or the scale factor) to make the dependent variable leave Lineland.
Go to the Reduce the Dimension sketch.
