The hardest thing for me to understand this unit was finding the domain with functions that had radicals in the numerator and denominator. I didn't understand how to combine the two domains once i found them. I'm still not positive how to do that. Also, just the union symbol and the other one confused me because i wasn't exactly sure what it meant and when to use it.
Stop in sometime before or after school and hopefully with a little hard work we can start to understand those pesky domains!
