Since, we can only use integers such as 1, 2, 3, ... in order to count for the number of pencils that is purchased. The domain of the equation is essentially the values of x that can be used. In this example, the answer is letter A.

2

Step-by-step explanation:

When you use 2 for x you get 5+6(2)=17

simplifying:

5+6(2)=17

5+12=17

17=17
