Best ResponseYou've already chosen the best response.1hint: using the definition of logarithm, we can write: \[\Large x + 1 = {3^y}\]

Best ResponseYou've already chosen the best response.0Oh the logarithmic is the in the inverse of exponential functions, so all you have to do is cinvert it to an exponential function and substitute the velue

Best ResponseYou've already chosen the best response.1\[f^{1}(2) =x \text{ implies } f(x)=2 \\ \text{ so we need to solve } 2=\log_3(x+1) \\ \text{ and converting to exponential form gives } \\ 3^2=x+1\]
