a. what is the domain of the relation
b. what is the range of the relation
c. is the relation a function? explain your answer.

The domain satisfies all of the x coordinates: (0, 3, 4, 5, 6) in order from least to greatest. The range satisfies all the y coordinates: (1,2) (You don't have to restate the 2)
Yes that relation is a function. The only time a relation is not a function is if you "reuse" an x value. In other words, a single x value cannot share more than one y value.

2L

Step-by-step explanation:

Each recipe = 500 mL of milk

Number of times you make recipe per month = 1

Number of months you make recipe = 4

Total milk used for 4 months = 500 mL * 1 * 4

= 2000 mL

Recall,

1L = 1000 mL

Therefore,

2000 mL = 2L

You should buy 2L container of milk
