Best ResponseYou've already chosen the best response.0that makes \[f(144)=\sqrt{144}+12=12+12=?\]

Best ResponseYou've already chosen the best response.0satellite73, don't you first subtract g(x) from the f(x) and then plug in 144 for x?

Best ResponseYou've already chosen the best response.0you can but no need right? \[fg(144)=f(144)g(144)\] i would compute each number, then subtract

Best ResponseYou've already chosen the best response.0we have \[f(144)=24\] all we need is \(g(144)\)
