# Ch 10: High School Algebra: Properties of Functions

Watch video lessons to learn about function notations, operations and terms. The lessons in this chapter cover computing functions, finding domains and ranges, transforming functions, and composing functions.

In algebra, a function is just a special type of equation. To help you better understand the roles, terms and operations of functions, we've dedicated a chapter of this high school algebra course to making the learning of functions simple. The short videos define functions and cover the basic processes for solving functions. Stories, examples and themes overlap in these lessons, making the operations and calculations easier to follow and absorb.

Start out by learning the essential principles of a function notation and the key terms used to describe functions and their components. There's also a lesson especially for transforming functions using options like rotation, reflection, dilation and translation.

Just the appearance of a function can be a bit intimidating, but our lesson on the methods for adding, subtracting, multiplying and dividing functions helps remove some of the confusion and makes learning the operations easy. The lesson on domains and ranges can also help take away a bit more of the menacing aspects of functions by showing you their limitations.

Soon you'll be able to compose your own functions, though if you need some help in that department, check out the lesson on the topic. You can also learn how to write, find and predict inverse functions.

Wrap up the chapter by applying function operations you've learned to solve some complex practice problems. Each lesson also includes a short quiz to test your understanding of the topics covered in each lesson. Thanks for using our video lessons to help you learn about functions. We hope you find them useful and fun.
