Best ResponseYou've already chosen the best response.0domain: you can only take the log of a positive number, so start with \(x+2>0\) and solve for \(x) in one step

Best ResponseYou've already chosen the best response.0for the inverse, set \[x=\ln(y+2)3\] and solve for \(y\)

Best ResponseYou've already chosen the best response.0this takes three steps \[x=\ln(y+2)3\] \[x+3=\ln(y+2)\] \[e^{x+3}=y+2\] \[y=e^{x+3}2\]
