  1. 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 …

  2. What is a function? (video) | Domain & range | 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 …

  3. Functions | Algebra 1 | Math | Khan Academy

    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! Power up your …

  4. Range of quadratic functions - Khan Academy

    Learn how you can find the range of any quadratic function from its vertex form. In this article, we will learn how to find the range of quadratic functions. In other words, we will learn how to determine the …

  5. Domain and range from graph (practice) | Khan Academy

    Given the graph of a function, determine its domain or range.

  6. Functions | Algebra (all content) | Math | Khan Academy

  7. How to find domain and range from a graph (video) | Khan Academy

    Finding the domain and the range of a function that is given graphically. Created by Sal Khan.

  8. Domain and range of quadratic functions (video) | Khan Academy

    Now, the range, at least the way we've been thinking about it in this series of videos-- The range is set of possible, outputs of this function. Or if we said y equals f of x on a graph, it's a set of all the possible …

  9. How to find the domain of a function (video) | Khan Academy

    The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0.

  10. Rational functions (video) - Khan Academy

    We break down the definition of the function given in set-builder form and plot the graph by connecting points on the cartesian plane. Domain and Range is calculated through visually observing the graph.
