Great Posts!!!!!

Katrina, that was a fabulous post. I'm not sure if you wrote this blog tonight or back in semester one but it was great. The diagrams were out of this world, excellent job on that. Carla, I hope that helped a bit with your trouble with understanding interval notation.

Just remember that interval notation is just a simpler way of expressing domain and range. You use round brackets when that value is NOT included and square brackets when it is included.

If it still dosen't make sense by tomorrow, remember to bring it up after mental math! Great job again!!!
