The values that are in the domain of Aron's function are A.2, C.5; E.10.
What is the domain of a function?In mathematics, the domain of a function is the set of inputs accepted by the function.
Aron wrote the following function:
f(x) = 25x - 15
where,
x is the number of cars they wash.f(x) is the amount of money earned after washing x cars.We have to decide among a series of numbers, which below to the domain of the function. Since "x" represents the number of cars, we know that x must be an integer greater or equal to zero.
Then, the possible values are A.2, C.5; E.10.
The values that are in the domain of Aron's function are A.2, C.5; E.10.

Step-by-step explanation:
If x represents the number of cars that wash Aron, then the domain of x must contain only integers and positive numbers (natural numbers)
This, because Aron can not wash -3 cars, it would be absurd then for x to be a negative number.
In the same way Aron can not wash 1.29 cars. Or washed 1 car or washed 2, it is not consistent in this case to say that washed a car and a half, for example.
Therefore the correct answer is the options.
A.. 2
C.. 5
E.. 10
