what is the practical domain for the function f(x)?

a. all positive integers that are multiples of 5

b. all whole numbers

c. all positive integers

d. all real numbers

B

Step-by-step explanation:

The domain is all possible values of x.  Here, x is the number of $5 nontaxable items.  So x must be an integer, and it can't be negative.  It is possible for x to be 0.  So x is all whole numbers.
