Answer:
The domain would be the set of all positive integers including 0.
Step-by-step explanation:
Given,
The membership fee = $ 10.00,
Charges for a movie = $ 1.50,
Thus, the total cost for renting x movies = ( 10.00 + 1.50x ) dollars,
If C(x) represents the total cost to a member of renting movies,
[tex]\implies C(x)=(10.00+1.50x)[/tex]
Since, the number of movie can not be negative or a fraction,
⇒ The value of x must be an integer including 0,
Also, domain of a function is the set of all possible value of input values,
Thus, the domain of the function C(x) is the set of all integers include 0.
