Where do you need help?

anonymous · Answer

you plug in the 3 and -3, so then you graph how?

anonymous · Answer

c is the vertical shift of the graph x cube stretched by a factor of 2...

anonymous · Answer

I guess i'm confused where the horizontal part of the graph goes?

anonymous · Answer

is this for college algebra?

anonymous · Answer

yes

anonymous · Answer

your told to sketch the graph... so you don't have to find any values what is expected is that you know the keypoints of the graph x^3.

anonymous · Answer

So that means you would know vertical compression when f(x)=2f(x) This implies that the graph is stretch by a factor of 2 and when f(x)=1/2f(x) this implies that the graph is compressed by a factor of 1/2. And f(x)+c is vertical shift of the graph negative down, positive up. Does that help?

Could you dumb it down a little?

anonymous · Answer

the graph of x^3 should looks something like this: |dw:1340251225725:dw|
