Domain and range. The domain and range of a function is all the possible values of the independent variable, x, for which y is defined. The range of a function is all the possible values of the dependent variable y. In other words, the domain is the set of values that we can plug into a function that will result in a real y-value; the range is ...

How to Find Domain and Range of a Function? - Cuemath
https://www.cuemath.com/calculus/domain-and-range-of-a-function/
What is Domain and Range? The domain and range of a relation are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = { (1, 2), (2, 2), (3, 3), (4, 3)}, then: Domain = the set of all x-coordinates = {1, 2, 3, 4} Range = the set of all y-coordinates = {2, 3}

How to find domain and range from a graph (video) - Khan Academy

Domain is all the values of X on the graph. So, you need to look how far to the left and right the graph will go. There can be very large values for X to the right. Range is all the values of Y on the graph. So, you look at how low and how high the graph goes. Hope this helps.

Domain, Range and Codomain - Math is Fun
https://www.mathsisfun.com/sets/domain-range-codomain.html
Domain, Codomain and Range. There are special names for what can go into, and what can come out of a function: What can go into a function is called the Domain. What may possibly come out of a function is called the Codomain. What actually comes out of a function is called the Range. Example. • The set "A" is the Domain,

We can often write the domain and range using interval notation, which uses values within brackets to describe a set of numbers (see Section 0.2). For example, if a person has $100 to spend, he or she might express the interval that is more than 0 and less than or equal to 100 and write \(\left(0, 100\right]\).

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.

Definitions of Domain and Range. Domain. The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x -values which will make the function "work", and will output real y -values. When finding the domain, remember:

What are the domain and range? The domain of a relation (and thus also the domain of a function) is the set of allowable inputs; it is the set of all the x -values in the (x, y) points determined by the relation.
