Step-by-step explanation:
Answer:
Each can of soda costs about 33 cents.
Step-by-step explanation:
This is just a simple division problem, and you can find the answer by dividing the cost of the sodas by the total number of sodas, so 4/12. If you complete that problem, the answer is 0.33 repeating, and since it asks you to round to the nearest hundredth, the answer is just 0.33. It is in dollar amounts, so the answer is 33 cents.
Domain: 
Range: 
The relation is not a function.
Explanation:
The coordinates
are plotted in the graph. The image of the graph is attached below.
The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are 
The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are 
The relation
is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.
