Can anyone help me with these? My Math professor gave us these examples but he didn't show us how to solve them, and I'm a bit confused on how to graph them. Can anyone help me find the answers? 1. g(x) = x [|x|] 2. h(x) = [|x|] - |x| 3. g(x) = x - 2 sgn (x) Please help me find the answer to at least 1 of the items above. Hahaha, I am just so bothered. -_-

haha,yeah,there are times that if we keep on thinking we don't know the answer to a certain problem,we seek for help. but then after how many hours,we'll realize on ourselves that we really know the answer all along. we just don't listen to our own thoughts sometimes,which makes us realize things can be solved on our own. but still,it's nice to ask for help sometimes.good luck with that!

Exactly! Haha, but yes sometimes it's really good to ask for help so we can learn others' ideas as well. :D

yes,that's the good of helping each other out. we can ask for help and learn things from others we don't realize ourselves...but in the end,it's all up to us what to do to solve a problem...

jeeyah there are some p laces on the web that tutor you in algebra and trig and geometry and probably are better at explaining it than any of us could be. try looking for tutoring in algebra
