For each tank, calculate the average change in height from time t seconds to t + 0.001 second. express the answer as a number times the value of the original function at time t.
explain the meaning of these findings.

question:

could we have options?

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.
