What is a Function in Algebra?

This clip is just a few minutes of a multi-hour course.  
Master this subject with our full length step-by-step lessons!



Lesson Summary:
In this lesson, you'll about the very important topic of Functions in Algebra.  We'll explain what a function is, what is means, and why it is a useful concept in math.  Then, we'll work example problems where we evaluate a function at a few different values of the variable and calculate the answer.

Functions are extremely useful in algebra and are in fact one of the most useful ideas in all of math.  Functions are use for practical reasons such as calculating the strength of a bridge, or calculating how high a rocket will fly.  Functions are also used in computer programming to calculate quantities.

This lesson lays the foundation of these ideas in Algebra.
