Transformations: How to Shift Graphs on a Plane

1. Transformations: How to Shift Graphs on a Plane

What is a transformation? Well, it's something that transforms one function into another! To see what I mean and how that looks, check out this lesson!

How to Add, Subtract, Multiply and Divide Functions

2. How to Add, Subtract, Multiply and Divide Functions

Adding, subtracting, multiplying and dividing functions is about as simple as substituting in expressions and then just doing whichever operation it asks you to do. Check out this video lesson to see some examples of this and learn just how easy it is!

Translating Piecewise Functions

3. Translating Piecewise Functions

Piecewise functions are two or more functions that only use part of a domain. If these functions need to be changed, we can translate them without even having to know the equation.

How to Compose Functions

4. 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.

Domain & Range of Composite Functions: Definition & Examples

5. Domain & Range of Composite Functions: Definition & Examples

Learn what makes a function a composite function and also learn how the parts of a composite function determine its domain. Also in this video lesson, learn about the range of composite functions.

Compounding Functions and Graphing Functions of Functions

6. Compounding Functions and Graphing Functions of Functions

We know that functions map numbers to other numbers, so what happens when you have a function of a function? Welcome to functions within functions, the realm of composite functions!

Inverse Functions

7. Inverse Functions

Inverse functions are two functions that do exactly opposite things. Check out this lesson to learn about how to write inverse functions, find inverse functions, and predict whether or not they exist.

Understanding and Graphing the Inverse Function

8. 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.

How to Identify Families of Functions

9. How to Identify Families of Functions

Functions come in all kinds of varieties, but they can be grouped together into families that have common characteristics. The difference and similarities can be seen in the equations and graphs of these functions. In this lesson, you will learn about the characteristics of different families of functions and how to recognize them based on their equations and graphs.

Modeling the Real World with Families of Functions

10. Modeling the Real World with Families of Functions

Families of functions are exactly as their name indicates, groups of functions that are all related in a specific way. Let's look at families of functions and use examples to see how to use them to model and analyze real-world phenomena.
