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 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.
Functions | TG Math Class 11 | Khan Academy
Types of Functions Learn Surjective (onto) and injective (one-to-one) functions Identity and constant functions
Rational functions, equations, and inequalities | Khan Academy
Rational functions model relationships defined by ratios of polynomials, often capturing complex behavior such as asymptotes and discontinuities. In this unit, you’ll analyze their key …
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.
Introduction to piecewise functions - Khan Academy
But what we're now going to explore is functions that are defined piece by piece over different intervals and functions like this you'll sometimes view them as a piecewise, or these types of …
Graphs, attributes, and applications of functions | Khan Academy
Functions come to life when we look at their graphs. In this unit, we’ll explore how features like symmetry, discontinuities, and intervals reveal deeper insights into function behavior.
Calculating the rate of change of a linear function
Learn how to calculate the **rate of change** (also called the **slope**) of a linear function three ways — in a table, on a graph, and as an equation.
