Ch 7: Functions

Watch video lessons and learn how to use, handle and figure functions in algebraic equations. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these topics.

Functions

How much do you know about functions? If your knowledge of functions is obsolete or a little rusty, you need to watch our video lessons. We have videos that cover everything from defining a function to using it in complex equations. You'll see example problems throughout our lessons that will demonstrate the concepts being taught.

Check out our lesson on using function notation. Find out when to use it and in what cases it's the most useful. Study transformations and learn how to shift graphs on a plane. Also watch our lessons to learn how to add, subtract, multiply and divide functions.

If you need to get a bit more familiar with functions, watch our lesson that answers the question 'What is domain and range in a function?' Let this lesson show you what values are not allowed in a function, such as a zero denominator and negative root.

Can you compose a function? If not, we've got a lesson that covers that, too. We also have a lesson that covers inverse functions. Learn what an inverse function is and how to find one. Also, catch our lesson that goes over applying function operations. All these lessons give you practice problems, so you can get a clear view of each step and concept being explained.

By the time you've watched our lessons on functions, you'll completely understand why functions are often compared to machines. You'll see how they serve a major role in going from problem to solution. Thanks for watching our video lessons!
