anonymous · Answer

i think x is gonna be -3,3, z is 0 to 9-y^2, but not sure on y.

anonymous · Answer

$$\int\limits\limits_{-3}^{3}\int\limits\limits_{-\sqrt(9-z)}^{\sqrt(9-z)}\int\limits\limits_{0}^{9-y^2}x^2e^ydzdydx$$

try
$$\int\limits\limits_{-3}^{3}~~\int\limits\limits_{-3}^{3}~~\int\limits\limits_{0}^{9-y^2}x^2e^ydzdydx$$

anonymous · Answer

yes, that's correct.  ok, why are my y bounds not equations?  i drew it out in an online grapher and the y was bounded by the parabola....or was i looking at it wrong?
