If f(x) = 3x - 9 and g(x) = -x?, find:
a) f(-2)
b) g(-2)
c.) x if f(x)=0

Step-by-step explanation:

a) f(-2) = 3(-2) - 9 = -15

b) g(-2) = -(-2) = 2

c) 0 = 3x - 9

   9 = 3x

    x = 3

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

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.
