1. Problem Description

The problem asks to find the inverse of the function f(x)=3x12x6f(x) = \frac{3x-1}{2x-6}.

2. Solution Steps

Let y=f(x)y = f(x). We have y=3x12x6y = \frac{3x-1}{2x-6}. To find the inverse, we need to solve for xx in terms of yy.
y(2x6)=3x1y(2x-6) = 3x-1
2xy6y=3x12xy - 6y = 3x - 1
2xy3x=6y12xy - 3x = 6y - 1
x(2y3)=6y1x(2y - 3) = 6y - 1
x=6y12y3x = \frac{6y - 1}{2y - 3}
Now, we replace xx with f1(y)f^{-1}(y). So, we have f1(y)=6y12y3f^{-1}(y) = \frac{6y-1}{2y-3}. Finally, we replace yy with xx to express the inverse function in terms of xx.
f1(x)=6x12x3f^{-1}(x) = \frac{6x-1}{2x-3}

3. Final Answer

f1(x)=6x12x3f^{-1}(x) = \frac{6x-1}{2x-3}
