Question

i give medals! find the inverse function of y=ln(x-4)

Answer 1

write in equivalent exponential form as
\[e^y=x-4\] then solve for \(x\) in one step

Answer 2

Interchange the x and y variables, then solve for new y

Answer 3

@satellite73, do you mean y?

Answer 4

no

Answer 5

then is it x=e^y + 4?

Answer 6

you are trying to solve for \(x\) to find the inverse
if you want to do it by interchanging \(x\) and \(y\) you get the same thing
start with
\[x=\ln(y-4)\] then write in exponential form as
\[e^{x}=y-4\] and get
\[y=e^x+4\]

Answer 7

oh ok, thanks :)
