Okay here, I want to find the domain of this function. And the key thing is in math, you can't divide by zero and the domain you can't have a square root of a minus number. So knowing that I know that three x squared minus 12 cannot be zero or negative. So it must be more than zero, which means three x squared more than 12 X squared must be above four, Which implies X is more than two, or X is less than -2. And that is my domain numbers above two, numbers below minus two. Mhm
