Question 1189777
.
whats the inverse for f(x) = 4x -2
~~~~~~~~~~~~~~~~~~~~


<pre>
We write

    y = 4x - 2.


Then we swap x and y

    x = 4y - 2


and express "y" from here

    y = {{{(1/4)*(x+2)}}}.


What you get is your  <U>ANSWER</U>.

Solved.

The procedure described in my post is the standard to create an inverse function 

(when it exists), &nbsp;and the wording mantra is standard and universal, &nbsp;too.


So, &nbsp;it is worth to &nbsp;MEMORIZE &nbsp;it to use for the future similar problems.
