Question

The number of school buses needed to transport students on a field trip is given by the function f(x)=x+3/30 what is the domain of this function
A. X is the set of all real numbers
B. X is the set of all integers
C. X is the set of all non-negative integers
D. X is the set of all non- negative real numbers

Answer 1

1. You have the following function that is shown in the problem above:

f(x)=(x+3)/30 

 2. Then, the domain of the function f(x)=(x+3)/30 is:

 All the real numbers (R)

 3. Therefore, the correct answer for the exercise is the first option (Option A), which is:

 A. x is the set of all real numbers.
