Writing Domain And Range Notation

We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers.

Writing domain and range notation. Interval notation is a method used to write the domain and range of a function. Use notations to specify domain and range in the previous examples we used inequalities and lists to describe the domain of functions. The letter u indicates a union that connects parts of a domain that may be separated by a gap.

We can also use inequalities or other statements that might define sets of values or data to describe the behavior of the variable in set builder notation. Write the range with proper notation. Answer domain range.

The range of f x x 2 in set notation is. Open parentheses closed parentheses infinity imagine an 8 sideways negative infinity an 8 sideways with a negative sign in front of it and union a symbol similar to an elongated u. In functions and function notation we were introduced to the concepts of domain and range.

When using set notation inequality symbols such as are used to describe the domain and range. Like the domain the range is written with the same notation. Give the domain and range of.

For example if a person has 100 to. Write your answer using set notation. Y y 0 r indicates range.

Write domain and range given an equation. 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. In interval notation we use a square bracket when the set includes the endpoint and a parenthesis to indicate that the endpoint is either not included or the interval is unbounded.
