I need help on finding the nonlinear

Option A

Step-by-step explanation:

To find out if a function is nonlinear, you can graph the points in the table. If it forms a straight line, then it is linear. If it does not, then it is nonlinear.

1) Let's graph three points from Option A's table. Graph (1,3), (2,9), and (3,27) and see if you can draw a completely straight line passing through them. When you do, you will have something similar to the picture below. The line they form is not straight, therefore Option A is a nonlinear function.

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.
