Is the function linear or nonlinear? If linear, state the constant rate of change. Linear, 1

Linear, 2

Nonlinear

Linear, -2

Nonlinear

Step-by-step explanation:

You can see that at first, when x goes up by 2 y goes down by 2, but then after that x goes up by 2 and y goes down by 3, meaning it won't be a line because it goes down by different amounts.

(3x-8) or (3x+8)

step-by-step explanation:

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.
