Use notations to specify domain and range. In interval notation we use a square bracket. When using set notation we use inequality symbols to describe the domain and range as a set of values.
Interval notation is a method used to write the domain and range of a function.
Find the domain and range of the quadratic function. Set Builder Notation is very useful for defining domains. Another way to identify the domain and range of functions is by using graphs. In interval notation we use a square bracket.
