# Thread: Functions and Inequalities.........URGENT NEED MUCH HELP.

1. ## Functions and Inequalities.........URGENT NEED MUCH HELP.

OK, so I'm new to this whole thing, so I thought I might as well ask a question as to what functions are. I've got a TEST tomorrow, and I don't understand the material. I get the basic concept, and I used this site to help me (and it did... a lot) BUT any extra pointers would be appreciated. Another thing, is, there are these graphs that are shaded up or down from a line and the answer to solving one of those would be 1<x<3 ????? I think. ????????? Really don't get those. Those are inequalities by the way. And, if I were to graph a function, or find something like this for example: y=f(x), find f(3), how would I do that? AND..... how would I find the domain and range on a graph???????????

Why to you use those stupid smiles and curtsy fonts?
Maybe you do not understand the material because you are not taking this seriously. Do you?

3. ## Oh....

I used those emoticons to show I was angry, frustrated, and sad. I really do take this stuff seriously, that's the reason I asked for help.

Fair enough! Then repost the question in a readable form.
