If f(x) = x − 4, what does f(3) represent? the value of (x − 4) when x = 3 the value of x when (x − 4) = 3 the value of 3f(x) when x = 3 the value of f(x) when (x − 4) = 3

f(3) represents the value of (x − 4) when x = 3.

Step-by-step explanation:

Given function,

After Substituting x = 3 in the above function,

f(3) would represents the value of f(x) when x = 3,

In the above function, the value of f(x) is (x-4)

Thus, we can say that,

F(3) represents the value of (x-4) when x = 3,

First option is correct.

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.

answer: its the third option.
