Question

What is the inverse function of `f(x)=4x+3`?

Answer 1

`=>f^-1(x)=(x-3)/4` is the inverse function

Explanation:

`f(x)=y=>y=4x+3` because `f(x)` is another way of writing `y`

The first thing you have to do is to switch `y` and `x` then find the new value of `y`, which gives you the inverse of your function `=>f^-1(x)`

`x=4y+3`

`4y=x-3`

`y=(x-3)/4`

`=>f^-1(x)=(x-3)/4`

Hope this helps :)
