Pre-calculus Review part 1: Domain and Range

[poisonparody]

So helpful! My professor breezed over finding the range when dealing with something under a radical like you did at the end there. Thank you!

Hello, nice presentation, explaining is very clear, please put your video recorder in little way back, next time. because it moves lot while your every moves, it s really annoying while focus on the video ( class). what s happen the camcorder try to centralizer you that every time you move. I d say it wont moves lot when you place little way back than now. please don't for forget to zoom it (lol).Thanks again for your presentation, very clear :)
