Find the domain of f(x). f(x) = √9x+36

The domain in interval notation is [-4,∝) or set build: {x|x

Step-by-step explanation:

I'm assuming the 9x and the 36 are in the root

first we must solve for x

substract 36 to both sides

divide by 9 to both sides

simplify left side

simplfy right side

The domain in interval notation is [-4,∝) or set build: {x|x-4}

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
