Best ResponseYou've already chosen the best response.1start with the fact that \(\log_3(\sqrt{x})=\frac{1}{2}\log_3(x)\)

Best ResponseYou've already chosen the best response.1i mean is it \[f(x)=\log_3(\sqrt{x}+3)\] or \[f(x)=\log_3(\sqrt{x})+3\]

Best ResponseYou've already chosen the best response.1ok then start with \[f(x)=\frac{1}{2}\log_3(x)+3\]

Best ResponseYou've already chosen the best response.1we can do the usual trick of writing \[y=\frac{1}{2}\log_3(x)+3\]then \[x=\frac{1}{2}\log_3(y)+3\] and solve for \(y\)

Best ResponseYou've already chosen the best response.11) subtract 3 2) multiply by 2 3) raise 3 to everything

Best ResponseYou've already chosen the best response.1\[x=\frac{1}{2}\log_3(y)+3\] \[x3=\frac{1}{2}\log_3(y)\] \[2x6=\log_3(y)\] \[3^{2x6}=y\]

Best ResponseYou've already chosen the best response.1last step because \[\log_b(y)=x\iff b^x=y\]
