Question

A carton of eggs contains 12 eggs. Each carton of eggs costs $1.89.A function, f(x), is written to represent the cost of purchasing x cartons of eggs.What is the practical domain for the function f(x)?all whole numbersall real numbersall whole numbers that are multiples of 12all positive integers

Answer 1

Given the information on the problem, we have the following function:

$f(x)=1.89x$

where 'x' represents the numer of cartons of eggs.

Notice that this is a real function, but it can only take integer values. Therefore, the practical domain of the function f(x) is positive integers
