What is the domain in interval notation?

Interval notation. When using interval notation, domain and range are written as intervals of values. For f(x) = x 2, the domain in interval notation is: D: (-∞, ∞) D indicates that you are talking about the domain, and (-∞, ∞), read as negative infinity to positive infinity, is another way of saying that the domain is "all real numbers." The range of f(x) = x 2 in interval notation is: R: [0, ∞) R indicates that you are talking about the range.
