f(x - 1) = (3x + 1) / (x - 2)
f(x + 1 - 1) = (3 (x + 1) + 1) / (x + 1 - 2)
f(x) = (3x + 3 + 1) / (x - 1)
f(x) = (3x + 4) / (x - 1) **jika itu yang ditanyakan, tapi jika ditanyakan inversnya**

f (x) = (ax + b) / (cx + d)
f^-1 (x) = (-dx + b) / (cx - a)

f(x) = (3x + 4) / (x - 1)
f^-1 (x) = (x + 4) / (x - 3)
