Let f(x)=25000+3000 x x , where is the number of siblings of the student, dimensionless, and is the financial aid for the student, measured in US dollars.
represents the domain of the function, whose set is formed by non-negative entire numbers:
In other words, the domain of the function is represent by all values of equal or greater than zero.
