We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers. 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. The domains and ranges used in the discrete function examples were simplified versions of set notation.
Given a function in function notation form identify the domain and range using set notation interval notation or a verbal description as appropriate.
