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 …
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.

Inputs and outputs of a function Learn Worked example: matching an input to a function's output (equation)
Equations vs. functions (video) | Functions | Khan Academy
A function by definition is a relationship where each input value (x) creates one output value (y). For the equation x=7, every point on the line has an x-value = 7 and the y-values will be different.
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 …
Linear equations and functions | 8th grade math | Khan Academy
When distances, prices, or any other quantity in our world changes at a constant rate, we can use linear functions to model them. Let's learn how different representations, including graphs and equations, …
Advanced function types | College Algebra | Math | Khan Academy
Let's use the building blocks of simpler function types to explore functions that zig-zag or twist across the screen. Come explore the weird and wonderful world of absolute value graphs, piecewise functions, …
Functions: FAQ (article) | Functions | Khan Academy
A function is a mathematical rule that matches inputs to outputs. We can think of it like a machine: put a number in, the machine does some calculations, and out pops a corresponding number.
