Throughout this week the thing I've had the most problem with is finding the domain of radicals. For the longest I just couldn't remember how to do it. I still sometimmes struggle with it but I am getting better. As long as I remember to the the quantiy greater than or equal to zero I can do it. Then I have to remember that the domain is the h value in a sqaure bracket with either negative infinity if the a value is negative or a positive infinity if the a value is positive.
