Answer 2

Answer:

Option: 1 is the correct answer.

       1.  all whole numbers

Step-by-step explanation:

It is given that:

A carton of eggs contains 12 eggs.

Also, cost of each carton is: 1.89

This means that the cost of purchasing x cartons is given by:

          f(x)=1.89x

As the number of cartons that one would buy would be as a whole.

Hence, the practical domain for the function f(x) is:

       1.   all whole numbers.
