This is 15 points please help Find f(6) if f(x)
) f==x+9
a. 12
b. 10.5
C. 6
d. 3

A. 12

Step-by-step explanation:

Step 1: Define

f(x) = 1/2x + 9

f(6) = x = 6

Step 2: Substitute and Evaluate

f(6) = 1/2(6) + 9

f(6) = 3 + 9

f(6) = 12

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.
