Answer:

Gah! Inverses!

Step-by-step explanation:

This is a pretty simple concept, just switch the x and f(x) values!

If you don't understand, look at how I solve it!

$f(x)=\frac{1}{3} -\frac{1}{21} x$

Switching the positions of the x and f(x) values...

$x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\$

Note: That f(x)^-1 is the proper notation for inverse functions.

$x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7$

There you go!

Hope this helps, and don't procrastinate!
