Question

a function $c(x)$ is used to represent the total cost, $c$, of buying $x$ pounds of rice at the bulk prices. due to limitations on the number of pounds of bulk rice customers are allowed to buy, the domain for $c(x)$ is $2,6$. which statement best describes the meaning of a domain of $2,6$? oa the number of pounds of rice that can be bought can be any value between 2 and 6 but not including 2 or 6. ob the number of pounds of rice that can be bought can be any value between 2 and 6 including 2 and 6. oc the total cost of rice that can be bought can be any value between 2 and 6 but not including 2 or 6. od the total cost of rice that can be bought can be any value between 2 and 6, including 2 and 6.

Explanation:

The domain of a function represents the set of all possible input - values. Here, the function $C(x)$ has $x$ as the input which represents the number of pounds of rice. The domain $[2,6]$ is in interval - notation. Square brackets indicate that the endpoints are included. So, $x$ (the number of pounds of rice) can take any value from 2 to 6, including 2 and 6.

Answer:

B. The number of pounds of rice that can be bought can be any value between 2 and 6 including 2 and 6.
