For this case we must find the product of the following expression:

We have to by law of signs of multiplication:

Also, by definition of multiplication of powers of the same base, we put the same base and add the exponents, then the expression is rewritten as:

Answer:

Answer:b
Step-by-step explanation:
Nonlinear has a break or is noncontinuous
For example x is not equal to 4
If you're using the shell method, the setup would be

Reasoning: consider just one shell (see the image below). The height of the shell is determined by the vertical distance between the curve
and the line
. The radius of each shell is determined by the value of
, which can only range from 1 to 2 within the region of interest, and the height is determined exactly by
at this
. Multiply by
to get the surface area of this infinitesimally thin cylindrical shell, then integrate along the interval [1, 2] to get the volume.
We have
