well, to find the inverse function u need to find another function so that f o g = x

the o denote composition

notice not every function has inverse tho

But to find it, u need to isolate x

u can call f(x) = y

for easier notation

then u will have y = (2x+3)/(x-4)

from here u isolate x

and then u can rename the variable, so x = y and y = x

now u do the same with ur example
