how do you write the domain of set builder notation

by Sandrine Luettgen Published 3 years ago Updated 2 years ago

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.
