Answer:
The range is f(c) ≤ 250
Step-by-step explanation:
* The meaning of function
- It is a relation between to variables
- One of them is the input called the domain of the function
- The other is the output and called the range of the function
∵ f(x) = y
∴ The values of x are the domain of the function
∴ The values of y are the range of the function
* Lets look to the problem
- We have the relation between the ferryboat and the number
of the cars transported daily
- The greatest number of cars transported daily is 5000
- The domain of f(c) is c ≤ 5000
∵ c = 5000
∵ f(c) = c/20
∴ f(c) = 5000/20 = 250
- The range of the function is f(c)
- The maximum value of f(c) is 250
∴ The range is f(c) ≤ 250
