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

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.

the answer is that it is true
