B involves direct variation.
y and x are directly proportional.
Answer:

Step-by-step explanation:
Given the function: 
f(x) =number of days it would take to complete the project
x =number of full-time workers.

The domain of a function is the complete set of possible values of the independent variable.
In this case, the independent variable is x, the number of full-time workers. We have shown that x cannot be zero as there must be at least a worker on ground.
Therefore, an appropriate domain of the function f(x) is the set of positive integers (from 1 to infinity).

The answer would be C because the first figure is half of every number on the second figure making it similar it’s not congruent because there not the same size
