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. When using interval notation domain and range are written as intervals of values. Use brackets to enclose the numbers when the endpoint value is included.
Given a function in function notation form identify the domain and range using set notation interval notation or a verbal description as appropriate. How to find the domain and range of a function. We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers.
Parenthesis or and are used to indicate less than but not including and greater than but not including. For f x x 2 the domain in interval notation is.
