The function C(d)=8d+2 represents the cost to order a box of donuts d, including the flat rate shipping charge.

Does finding C(−2) make sense in the context of this function?

No, it does not make sense because you cannot order -2 boxes of donuts.
No, it does not make sense because you cannot order -2 boxes of donuts.

Yes, it makes sense because that is the cost of shipping.
Yes, it makes sense because that is the cost of shipping.

No, it does not make sense because -2 is not rational.
No, it does not make sense because -2 is not rational.

Yes, it makes sense because only irrational values are impossible.

No, it does not make sense because you cannot order -2 boxes of donuts.

No, it does not make sense because you cannot order -2 boxes of donuts.

No, it does not make sense because you cannot order a negative number of boxes of donuts. In the context of this function, the variable d represents the number of boxes of donuts ordered, and it doesn't make sense to have a negative number of boxes. Therefore, finding the cost of ordering -2 boxes of donuts is not meaningful.
