Answer:
0 ≤ n ≤ 72 where n is an integer
Step-by-step explanation:
Given : C(n) = 25n
To Find: what is the domain of c(n)?
Solution:
Domain of the function is defined as the values of n which we can use to substitute in the equation
Now, in equation C(n) = 25n , n represents the number of cars.
This means that n has to be positive integer because we can neither have negative number of cars nor fraction of a car.
This means , n would start from 0 .
The second thing is that the maximum capacity is 72. This means that n cannot exceed 72 cars in the drive-in
So, we can say that n can be any integer starting from 0 till 72 (inclusive)
Hence our domain is: 0 ≤ n ≤ 72 where n is an integer
