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.
Exponential Functions
What if you created a function where the exponent is a variable? As you might expect, this would be called an exponential function. When you hear someone talk about “growing exponentially,” they are talking about an exponential function. Exponential functions have some very interesting patterns.
Equivalent Fractions
Fractions are ratios that’s why we call them rational numbers (ratio numbers). If you think about fractions as ratios, how does this help you to understand them?
