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

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 …

The domain is the possible numbers that the function will work for. Sometimes it is limited. For the function f (x) = 1/x, you cannot divide by zero, so the range would be all real numbers except …

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.

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 …

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

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?

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

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

- [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.
