B. cost(distance) is the right answer
Step-by-step explanation:
We are given that the cost is dependent on the distance traveled.
There are two types of variables.
Independent and dependent variables
Independent variable is the variable whose value is independent of any variable in the function while the dependent variable is determined by changing the values of independent variable
In the given scenario, cost is a dependent variable and distance traveled is independent.
When function notation is written, the independent variable is written inside the round brackets. In this case,
cost(distance) as cost is dependent on distance
Hence,
B. cost(distance) is the right answer
