Hey guys, I need some help on this graphing stuff. Any help is MUCH appreciated.

1. Sketch f(x) = { -x-3 if x < 0 }{lxl if 0 <or= x <2}{3 if x >or= 2}

If I'm not mistaken, doesn't the last piece get ignored since it goes against the first two?

2. f(x) = -(x+2)^3 +1

a. What type of function is it? <--- i don't really know what she's looking for... maybe a cubing function?

b. Sketch, showingallintermediate graphs. <---- again, unsure what ALL intermediate would mean...

3. g(x) = square root(4 - x) +2

a. Domain <--- this one i think i got, (-inf. , 4)U(4, inf.) right?

b. find the y-intercept <--- do you do this by setting x = 0?

c. Sketch, showing all intermediate graphs

Again, thanks a lot for ANY help at all. Kinda lengthy, sry....
