k(x)

Step-by-step explanation: I haven’t done Alg. 1 for a while, but I’m pretty sure that k(x) is the answer... when you have a negative in the parenthese, the line moves to the right. I hope this is correct and that it helps!

0.6, 3/5, and 6% are the 3 same portion.

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.
