If f(x) = 5х – 2 and g(x) = 2х + 1, find (f – g)(x).

Should be -3x-3.

Step-by-step explanation:

All you have to do is subtract like you would binomials, which is just 5x-2x and -2-1. I hope this helps!

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.

the answer is 13 cm
