State the domain of each function. g(x) = sqrt (x^2 - 9) I'm a little confused. Do I just need to plug in random numbers?

domain is : \[x^2-9 \ge0 \rightarrow |x|\ge3 \rightarrow x \in(-\infty,-3]\cup[3,\infty)\]

the range is usually found by finding the domain of the inverse, however , in this question you can notice that the minimum occurs at x=0 which is -9 , and THE VALUE of function increases no matter where x goes , that is , the range is: \[[-9,\infty)\]
