The answer is y = 3x+3

So, option C

Step-by-step explanation:

Just by observation,

Let's assume the answer is y = 3x + 3

Replacing x with -1, we have

y = 3 (-1) + 3

y = 0

Replacing x with 0, we have

y = 3 (0) + 3

y = 3

Replacing x with 1, we have:

y = 3 (1) + 3

y = 6

Just like in the table.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
