my homework asks me to graph that equation and x=0 so i can rotate it around the x axis and find the volume of the solid using shells. All i wanna know is how to graph it. thx

pretend that x and y are reversed, that is graph
y = 4x^2 - x^3
a simple cubic
Then flip it around the x=y diagonal
When I say "flip" I really mean "mirror", ie, mirror the result around the x=y diagonal.
The "flipping" part is unneccessary if you decide to compute the volume of rotation about
y = 4x^2 - x^3
and
y = 0
This is the same thing as the stated problem.

Put x=0 then y=0 and y=4 on factoring and solving we got this
The curve is passing through (0,0) and (0,4) The base curve is x=y^3

Do you know how to do that thingy where you get the inverse? My brain is fried from summer so I can't remember anything....

i wish i would've had Yahoo! Answers in high school math. All we could do is copy each other's work

I don't see the problem. Just use y as your variable and determine x.
