a) All real numbers
b) Positive integers
c) Non-negative integers
d) Positive real numbers

Answer 1

The domain of the function c(m) representing the cost of m months of grocery delivery is the set of non-negative integers.

Step-by-step explanation:

The domain of the function c(m) representing the cost of m months of grocery delivery is the set of possible values for the input variable m. In this case, the domain represents the possible values for the number of months of grocery delivery. Since it would not make sense to have a negative or non-integer number of months, the domain of c(m) is the set of non-negative integers. Therefore, the correct answer is c) Non-negative integers.
