How do you do this question?

y(0) = 3

Step-by-step explanation:

This is solved by plugging in each option one by one, and seeing which one results in a positive value for dy/dt.

dy/dt = (4 − 1) (1 − 2²) = -9

dy/dt = (7 − 1) (1 − 1²) = 0

dy/dt = (1 − 1) (1 − 2²) = 0

dy/dt = (-4 − 1) (1 − 0²) = -5

dy/dt = (3 − 1) (1 − 0²) = 2

Only the last option fits.

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.
