find the function inverse ,f-1(x) , of y = 2x + 1.

Step-by-step explanation:

It is called an inverse or reciprocal function of to another function that fulfills that:

If , then

To calculate the inverse of the function

So, rewritting the function

Changing the x for y

Let's clear y

Ordering the function above

So, the inverse of the function is:

.
