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.
What is a function? (video) | Functions | Khan Academy
Rearranging to solve for the variable you want to measure, you get a function (as long as there's not multiple outputs for any input)! Functions involve anything with an independent and dependent …

A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions.
Equations vs. functions (video) - Khan Academy
The definition of a function is that it is a set of ordered pairs where each input (x-value) creates only one output (y-value). Based on this definition, a function does not need to be an equation.
Linear equations, functions, & graphs | Khan Academy
This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing linear …
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 …
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.
Relations and functions (video) | Khan Academy
That's not what a function does. A function says, oh, if you give me a 1, I know I'm giving you a 2. If you give me 2, I know I'm giving you 2. Now with that out of the way, let's actually try to tackle the …
