The number of students working the concession stands at a football game can be represented by f(x)=x/50, where x is the number of tickets sold. Describe the relevant domain of the function.

Is it x <=50?

1 answer

no. What if x = -20?
So, you must have x >= 0
Also, I assume the stadium has some kind of maximum capacity, say M.
Thus you need 0 <= x <= M

Of course, you might also have some kind of maximum number of students that can work at once, further limiting the domain.
