If the function f(n) models the size of a jar that holds n marbles to be sold in a toy store, which describes an appropriate domain for the function?

all integers where n>0

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

A)all integers where n>0

B)all real numbers where n>0

C)all rational numbers where n> 0

D)all rational numbers where n> 0

Please have a look at the attached photo.

Please keep in mind that the number of marbles must be positive because the object can not negative. Moreover, the number of marbles must be an integer number because we can not buy a decimal number of marbles such as 5.5 or 6.5 marbles.

=> the domain for the function must meet 2 requirements:

1. Positive interval

2. Integer number

=> we choose A
