Replace f(x) with y. Then solve for x.

anonymous · Answer

Replace $f(x)$ with $y$, like this:       $y = \frac{3x - 2}{6}$.
Then solve for $x$.

mathstudent55 · Answer

$f(x) = \dfrac{3x - 2}{6} $

$y = \dfrac{3x - 2}{6} $

Now, do you know how to solve this equation for x?

mathstudent55 · Answer

First, multiply both sides by 6.
Then, add 2 to both sides.
Finally, divide both sides by 3.
What do you get for x?

@Anickyan  can you check my answer

anonymous · Answer

@romanortiz65, I got this:

$$f⁻¹(y) = \frac{6y + 2}{3}$$

mathstudent55 · Answer

This is how you do it following the steps I listed above:

$y = \dfrac{3x - 2}{6} $

First, multiply both sides by 6.

$6y = 3x - 2 $

Then, add 2 to both sides.

$6y + 2 = 3x  $

Finally, divide both sides by 3.

$2y + \dfrac{2}{3} = x  $

$x = 2y + \dfrac{2}{3} $

$f^{-1}(y) = 2y + \dfrac{2}{3} $
