The inverse is found by interchanging x and y
f(x) = y
![\text{x = }\frac{2y - 3}{y + 1}](https://tex.z-dn.net/?f=%5Ctext%7Bx%20%3D%20%7D%5Cfrac%7B2y%20-%203%7D%7By%20%2B%201%7D)
Multiply both sides by y + 1
x*(y + 1) = 2y - 3 Remove the brackets on the left
xy + x = 2y - 3 Subtract xy on both sides
x = 2y - xy - 3 Add 3 to both sides
x + 3 = 2y - xy Factor out y on the right. Use the inverse distributive law
x + 3 = y*(2 - x) Divide both sides by 2 - x
![\dfrac{x + 3}{2 - x}\text{=y=f(x)}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%20%2B%203%7D%7B2%20-%20x%7D%5Ctext%7B%3Dy%3Df%28x%29%7D)
