**Domain:**

The **domain** of a function **refers to a set of input values** for which the function is real and defined.

We solve

We will keep the like terms together as a group.

Add

Hence, the domain is

Using interval notation we can write the domain as

**Range:**

The range of a radical function is

Hence,

Range:

Using **interval notation** the range can be written as
