What is a Function: Basics and Key Terms

1. What is a Function: Basics and Key Terms

Mapping numbers sounds complex, but we do it when we buy gasoline. We pump gasoline, and the gas station charges us based on the amount of gas that we pump. Learn how this relates to functions while reviewing the basics and notations in this lesson.

Identifying & Extending Different Types of Patterns

2. Identifying & Extending Different Types of Patterns

In this lesson, we will look at different ways patterns present themselves in the world around us. We will take a look at how to identify patterns and how to extend patterns and use this in some real-world examples.

Compare Properties of Functions Algebraically

3. Compare Properties of Functions Algebraically

In this lesson, we will explore algebraic and numeric properties and the evaluation of functions. We'll demonstrate function evaluations and the idea that every element of the domain has a unique element in the range.

Graphing Basic Functions

4. Graphing Basic Functions

Graphs are just like maps - when you know the language! Review how locations have x and y coordinates similar to latitude and longitude, and how to plot points in the Cartesian plane.

Understanding and Graphing the Inverse Function

5. Understanding and Graphing the Inverse Function

If you use a function to map a to b, is there a way to go back from b to a again? Learn how to find and graph inverse functions so that you can turn a into b and back into a.

Draw a Graph Based on the Qualitative Features of a Function

6. Draw a Graph Based on the Qualitative Features of a Function

Learn how to sketch the graph of a function based on a description of its behavior. You can do this even if you don't know any exact numbers for the input or output values!

How to Compose Functions

7. How to Compose Functions

Function composition is the process of putting two or more functions together. This video lesson will explain how this process works and also show you how to evaluate functions that have been composed.
