Find the inverse: f(x)=x+5/3x-1

f^-1x=

We have .

To find inverse function we substitute x with and vice-versa to get

Now solve for . Note that I will use instead.

So we find that .

Hope this helps.

f-1(x) = (x + 5)/(3x - 1).

Step-by-step explanation:

Let y = (x + 5)/ (3x - 1)

3xy - y = x + 5

3xy - x = y + 5

x(3y - 1) = y + 5

x = (y + 5)/(3y - 1)

So f-1(x) = (x + 5)/(3x - 1).
