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

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.

Actually, on a Cartesian plane, we only use the domain and range of real numbers (not rational numbers), so we do not include imaginary numbers. These are not on our normal Cartesian (x …

Determine the domain of a function according to the algebraic limitations of that function.

So what's is the domain? The domain of a function, you'll often hear it combined with domain and range. But the domain of a function is just what values can I put into a function and get a valid …

- [Instructor] In this video, we're gonna do a few examples finding domains of functions. So let's say that we have the function f of x is equal to x plus five over x minus two.

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 …

I understand finding the range of a function, but I'm still confused about how to find the domain. Using the first function from the example, what would be the domain and how would you find it?

Finding the domain and range of a piecewise function where each segment is linear.
