If f(x)=2x/7+4, which of the following is the inverse of f(x)?

f(x) = 2x/(7 + 4)

Replace f(x) with y

y = 2x/(7 + 4)

Switch x and y

x = 2y/(7 + 4)

Solve for y

Simplify first

x = 2y/11

* 11

11x = 2y

/2

5.5x = y

Turn y into f^-1(x)

f^-1(x) = 5.5x

900 degrees

step-by-step explanation:

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.
