The carnival ride tickets cost $5 each. Let C(n)=5n be the amount of money you spend on n tickets. What is the domain of this function.

To determine the domain of the function C(n), we need to identify all possible values for the variable n.

In this case, n represents the number of tickets you want to buy. Since the number of tickets cannot be negative (you cannot buy a negative number of tickets), the domain of the function C(n) is restricted to positive integers or zero.

Mathematically, we can express the domain as:

Domain(C(n)) = {n ≥ 0}

Therefore, the domain of the function C(n) is all non-negative integers.

Domain would be the x-values that the function can have. Thus the smallest number is no tickets purchased for 5(0)= 0 dollars. Then you are purchasing in increments of 5$ for each ride...
