Lesson: The Domain and the Range of a Radical Function Mathematics

Start Practising

In this lesson, we will learn how to find the domain and the range of a radical function either from its graph or from its defining rule.

Lesson Plan

Students will be able to

understand that, where is a positive integer and are real constants, the radical function of the form is defined when
- ; if is an even,
- takes any real value; if is odd,
find the domain and range of a radical function from its graph,
find the domain and range of a radical function from its function rule.
