This website is easy to use and does a good job of demonstrating how to find the domain of a function. It perhaps oversimplifies the situation since the domain is always a connected interval with integer endpoints. Also, I think the questions at the end could be more clear.

I spent 15 minutes reviews this page and was very interested. This website I was able to use and input problems and have it help me come up with a solution. It was a creative way to come up with the answer. It also made it fun because it was just context, I actually go to play around with it. I like thought that the material was fun and accurate. It should good models and was educational. This helped me understand functions a little bit better. I struggle with this area and it made it fun and easy for me to understand. I felt that the effectiveness was appropriate for learning. I would use this site again for help because it made it fun and easy to use for a first time user.

This site has very helpful features for learning the essentials of domains and
functions. The tutorial features, assuming one has the right plug-ins, are very
helpful. One of the best features of this site is that it doesn’t insult one’s
intelligence, and yet it is very helpful for those of us who struggle a bit
with math. My student teachers designed a lesson using this site, and they not
only were able to design a good lesson, they received excellent feedback from
their fellow students who had to independently follow the lessons.
