Answer 1

The numbers 0 and 8 could be part of the domain of the function f(x) = 24x. The numbers -24 and -21 are not part of the domain.

Step-by-step explanation:

The function f(x) = 24x represents the student teacher ratio at Excel Elementary. In this function, x represents the number of teachers and f(x) represents the number of students. To determine the domain of the function, we need to consider the possible values for x. In this case, x represents the number of teachers, which cannot be negative. Therefore, the numbers -24 and -21 are not part of the domain. The number 0 could be part of the domain, as it represents the scenario where there are no teachers. The number 8 could also be part of the domain, as it represents a situation with 8 teachers.
