How do you solve an inverse function?

f(x)= 2x+3

Step 1

To find inverse of the function f(x) follow the following steps given below

- Replace f(x) with y.
- Then replace every x with a y and replace every y with an x.
- Solve the equation from Step 2 for y.
- Replace y with f
^{-1}(x). - Then f
^{-1}(x) is the inverse of f(x).

Step 2

Given,

f(x) = 2x + 3

Replace f(x) with y, we get

y = 2x + 3

Now, replacing every x with a y and replace every y with an x.

x = 2y + 3
