- [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.

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.

Many examples of determining the domains of functions according to mathematical limitations.

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

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 acceptable input values that can be used for that function. An interval is a contiguous set of numbers (usually real numbers) and is often shown using interval …

The domain, just as reviewed, that's the set of numbers that we could input into the function and get a valid output. And it's clear here, see, we have to pick between integers or real numbers.
