Find the domain of the function using interval notation.

D_{f(x)} = [9, \infty)

Step-by-step explanation:

Here we have the square root of a function, in the following format:

For the square root, and roots of even numbers(root of 4, 6, ...), we have the following condition in the domain

In this problem, we have that:

So

So the domain is
