ok i am in serious trouble in my math class alos in spelling some of u might think of my word dier i don't think thats how you spell it but whatever. as i was saying i am totally lost in my class not to mention my homework . Could someone just define function, domain, range, and how to figure all of these out. I also have a major problem with piece wise functions. I see no use for them expect to make me go bald from ecessively pulling my hair out . anway if u were wondering i'm in analysis and i have a quiz tom which i will probably fail. i've been studying but i decided that i cannot do this alone. i know i'm really acting like a drama queen but i just can't figure this stuff out. so any help would be really really great. thanks.
