A shipping company charges based on calculations of the volume of a rectangular box and the sum of the dimensions of the
box. A square rectangular prism has a side length represented by the linear function f(x), and a height represented by the
linear function g(x).

Answer:

B. The sum function is linear but the volume function is not

Step-by-step explanation:

We are given that f(x) and g(x) are linear. Due to this, the sum function S(x) is linear.

And we know the shape of our figure, so we just need to multiply the dimensions for V(x) but the product of three linear functions results in a cubic function, and we conclude V(x) is not linear.

Glad to answer.
