## What is the domain and range in set notation?

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements “used” by the relation or function constitute the range.

What is set-builder form with example?

Set-builder notation is a mathematical notation for describing a set by representing its elements or explaining the properties that its members must satisfy. For example, C = {2,4,5} denotes a set of three numbers: 2, 4, and 5, and D ={(2,4),(−1,5)} denotes a set of two pairs of numbers.

### What is set-builder notation in math?

In set theory and its applications to logic, mathematics, and computer science, set-builder notation is a mathematical notation for describing a set by enumerating its elements, or stating the properties that its members must satisfy.

What is the range in set notation?

When using set notation, inequality symbols such as ≥ are used to describe the domain and range. Therefore, this statement can be read as “the range is the set of all y such that y is greater than or equal to zero.”

What is Z in set-builder notation?

Special sets N denotes the set of natural numbers; i.e. {1,2,3,…}. Z denotes the set of integers; i.e. {…,−2,−1,0,1,2,…}. Q denotes the set of rational numbers (the set of all possible fractions, including the integers). R denotes the set of real numbers.

### What is domain in set notation?

We can write the domain of f(x) in set builder notation as, {x | x ≥ 0}. If the domain of a function is all real numbers (i.e. there are no restrictions on x), you can simply state the domain as, ‘all real numbers,’ or use the symbol to represent all real numbers.

## How do you write the range of a function?

Overall, the steps for algebraically finding the range of a function are:

1. Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2. Find the domain of g(y), and this will be the range of f(x).
3. If you can’t seem to solve for x, then try graphing the function to find the range.
