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 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.
This topic covers: - Evaluating functions - Domain & range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition -
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.
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
Types of Functions Learn Surjective (onto) and injective (one-to-one) functions Identity and constant functions
About this unit 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. Unit guides are here!
Using function notation to describe rules (part 1) Learn Worked example: Evaluating functions from equation
In this video, you are working with functions. You should have gone thru the lessons on what is a function and what is function notation much earlier than this video.
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.
