What is a function? (video) | Functions | Khan Academy
Functions assign a single output for each of their inputs. In this video, we see examples of various kinds of functions.
Equations vs. functions (video) | Functions | Khan Academy
Equations and functions are not the same thing, but they can be related in several ways. Watch Jesse Roe and Sal talk about the difference between equations and functions.
Rational functions (video) - Khan Academy
What are rational functions? How do we plot them? What is their domain and range? Let's find out. We break down the definition of the function given in set-builder form and plot the graph by connecting …

How to find the domain of a function (video) | Khan Academy
Functions are defined within the real number system as this is what is used the majority of the time. We graph functions within the coordinate plane. Each number line in the coordinate plane represents the …
Review: Functions (article) - Khan Academy
We've defined the functions for you, because we thought they'd be useful, and now it's up to you to decide what custom functions you want to use in your own programs.
