Iwill give brainliest to whoever is correct.

the domain is the numbers you can use for x

x is how many papers you can buy

you can't buy negative papers

but the store only has 5 papers so the answer is all inegers from 1 to 5 including 1 and 5

integes are like -3,-2,-1,0,,2,3,4, but since we have 1 to 5 we have 1,2,3,4,5

it isn't all real numbers from 1 to 5 because you can't buy 3.141592 reams of paper

answer is first one
