Finally! OS is up lol What is the domain and range of sqrt(4-x^2)? I already got the domain, I'm just having trouble with the range. (No graphing device is allowed, I need to learn this w/o graphs). For the domain, I think it is (-inifinity, 2] U [2, + inifinity). Check me if I'm wrong

domain is incorrect to find the domain, remember that whatever is inside the square root must be greater than or equal to 0
