# Domain math example

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. We can also define special functions whose domains are more limited. Sort by: Tips &

## Domain, Range and Codomain

Examples State the domains of the following functions using inequalities. 1. f (x) = x 2 2. g (x) = √x 1. x 2 is defined for all x values, so its domain is (-∞, ∞). We use an open interval because x

## Student Stories

His teacher moves to fast explaining how to do the problems. The app is great but their is a flaw in the app, and it has to due with the pricing of the premium version, great for explaning problem steps when the teachers not there.

## How to find the domain of a function (video)

Domain of a Function more All the values that go into a function. The output values are called the range. Domain → Function → Range Example: when the function f (x) = x2 is given the values x = {1,2,3,} then the domain is simply
