We often see Lissajous figures in old sci-fi movies because they are so cool. As you play with them I think you will find them as fascinating as I do. They created those figures by graphing points as a function of a third variable (the parameter). We can do the same and in the process come to understand Parametric Functions.

Lease or Buy
If you are in the market for a new car, you often have a decision to make. Do you want to buy the car or lease it. I have, over the years, developed a simple model to help me decide. I call it my rule of 6.
Inverse of Linear Functions
What does a linear function look like when we interchange the inputs and outputs, that is make the x-axis the y-axis and vice versa.
Introducing Subtraction
What if you built a rule that would enable you to count backwards? How would it be the opposite of addition? What would happen if it goes past zero?
Graphing
Graphs as we know them were first invented by Galileo. They are powerful images of functions. I will introduce you to graphs by letting you graph different functions represented by a table. Fill in each table visualize its graph.
