Me and some of my classmates are stumped on this problem, which asks for the domain and range in interval notation. We are using web-work, an online program where you in-put your answers, and it immediately tells you whether tour answers are right or wrong. So, here's the problem:
I entered "(0, infinity)" for the Domain and "(-12, infinity)" for the range... both were wrong :/ I got those figures by plugging the equation into my graphing calculator and looking at the graph/number table. That, and the fact that any negative x value would not return a real number.
I assume it's ......?

Thanks for the help, I got it work! :)
