a)
To explain: The relation that pairs letter-number combination with food or drink items is a function.
a)
Answer to Problem 27E
The pairs letter-number has separate relation with one food to one drink item that’s why it is a function.
Explanation of Solution
Given information: The relation that pairs letter-number combination with food or drink items is a function.
Since the corresponding combination is only for letter-number for one drink or one food item.
Hence, the given pairs of letters-numbers are a function.
b)
To find: The dependent and independent variable.
b)
Answer to Problem 27E
