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?
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

Verified Answer :

A) All integers where n>0

[ Number of marbles can't be negative, fraction or in decimal so it must be positive integer where n is greater than the zero ]

Hope this helps!

Answer:

A) all integers where n>0

Step-by-step explanation:

Notice that the number of marbles must be positive, because -5 marbles won't make any sense because objects cannot be negative. Similarly, the number of marbles must be an integer number, because they cannot be decimal, they cannot be broken into parts.

Therefore, the right answer is A, the right domain for the function is all n > 0, where n  is an integer.
