The practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4 that is option A or D is correct
The domain is "set of all possible inputs value for the function".
According to the question,
A package of buttery round crackers contains 4 sleeves of crackers each
package of crackers cost $2.49. A function f(x) written to represent the cost of purchasing x packages of crackers.
In order to find the practical domain for the function f(x) only if analysis the value of domain function 'x' must positive number so contain 'all positive integers' and since a package of buttery round crackers contains 4 sleeves then domain must contain 'all whole numbers that are multiples of 4'.
Hence, the practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4.
