    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! …

  2. 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 …

  3. Functions | College Algebra | Math | Khan Academy

    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.

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

  5. Equations vs. functions (video) | Functions | Khan Academy

    Many functions are equations. But, they don't have to be. If you have a set of ordered pairs where each x-value relates to only one y-value, then you have a function. For example: { (2,5); (3,8); …

  6. Intro to composing functions (video) | Khan Academy

    Functions are the equations to get an input (x) to an output (which is y or F (x)). Sal uses an example x^2-1, which is a function, but for simplicity we can see this as simply an xy equation.

  7. Algebra 1 | Math | Khan Academy

    The Algebra 1 course, often taught in the 9th grade, covers Linear equations, inequalities, functions, and graphs; Systems of equations and inequalities; Extension of the concept of a …

  8. 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 …
