Describe the end behavior of the graph of f(x) = x^3 (x + 3)(-5x + 1) using limits.
lina2011 [118]

Answer: Rises to the left and falls to the right

Step-by-step explanation:

Use the degree and the leading coefficient to determine the behavior.

There is a good video called "Describing End Behavior Using Limit Notation" by Mario's Math Tutoring, and it helps to show you how to find the end behavior with limits.

Use the Divergence Theorem to calculate the surface integral S F · dS; that is, calculate the flux of F across S. F(x, y, z) = (
MAVERICK [17]

\vec F(x,y,z)=(2x^3+y^3)\,\vec\imath+(y^3+z^3)\,\vec\jmath+3y^2z\,\vec k

has divergence

\mathrm{div}\vec F(x,y,z)=6x^2+3y^2+3y^2=6(x^2+y^2)

Then by the divergence theorem, the flux of \vec F across S is equal to the integral of \mathrm{div}\vec F over the interior of S. In cylindrical coordinates, this integral is

\displaystyle6\int_0^{2\pi}\int_0^1\int_0^{1-r^2}r^3\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=\boxed{\pi}
