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 …
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.
Functions | Integrated math 1 | Khan Academy
In this unit, we learn about functions, which are mathematical entities that assign unique outputs to given inputs. We'll evaluate, graph, analyze, and create various types of functions.
Transformations of functions: FAQ (article) | Khan Academy
What do we mean by "shifting functions vertically?" Vertical shifting is similar to horizontal shifting, except we are moving the entire graph of the function up or down.
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.
How to find the range of a function (video) | Khan Academy
The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of …
