1. Functions: Identification, Notation & Practice Problems
A function is simply a rule that takes one number and turns it into another. But some special conditions must apply for it to be a true mathematical function. Learn about those conditions and how we write functions here!
2. 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!
3. What Is Domain and Range in a Function?
The domain and range are the possible outputs and inputs of a function. In this lesson, learn about what might restrict the domain and how to figure out the domain and range from a graph.
4. 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!
5. 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.
6. 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.
7. Applying Function Operations Practice Problems
In this lesson, learn how to apply all the different properties of functions to solve complex problems. From function operations and composition to domain and range, get your practice here!
8. What is Function Notation: Definition & Examples
After completing this lesson, you will be able to recognize function notation. You will also be able to evaluate functions correctly using function notation.
9. Discontinuous Functions: Properties & Examples
In this lesson, you will learn about what makes a function discontinuous. You'll also explore different types of discontinuity, look at properties of discontinuity, and better understand the concept through examples.
10. Monotonic Function: Definition & Examples
In this lesson, we will learn about monotonic functions, explore these types of functions, and discover how to identify them. After you have finished the lesson, you can test your knowledge with a quiz.
