Answer:
First option is correct.
Step-by-step explanation:
Domain is the set of x values for which the function is defined.
Hence, in order to find the domain, we see at which x values the graph originates and at which value of x the graph terminates.
The piece wise function is graphed between the values -4 and 4.
There is a hole at x = -4 hence, we'll not include this point in domain.
There is a solid circle at x = 4 hence, we'll include this point in domain.
Therefore, the domain of f(x) is
First option is correct.

Answer:
Volume of a right prism = 65 cubic inches
Its height is increased by a factor of 20.
To find:
The new volume of the prism if the other dimensions do not change.
Solution:
The volume of a prism is:
Where, B is the base area and h is the height.
A right prism has a volume of 65 cubic inches.
The height of prism is increased by a factor of 20. So, the new volume is:
The volume of the new prism is 1300 in³.
Therefore, the correct option is B.
