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

  4. Domain and range from graphs of quadratic and exponential functions

    Compare and contrast domain and range given graphs of partial quadratic and exponential functions, where the ends of the shown graph vary among points, and arrows.

  5. How to find the range of a function (video) | Khan Academy

    If you start from the quadratic parent function, y=x^2, then y cannot be negative. One way to include negatives is to reflect it across the x axis by adding a negative y = -x^2. With this y cannot be positive …

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

    Determine the domain and range of the function f of x is equal to 3x squared plus 6x minus 2. So, the domain of the function is: what is a set of all of the valid inputs, or all of the valid x values for this …

  7. 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.
