Best ResponseYou've already chosen the best response.1You know that \(g(x) = 5x\). What is \(f(5x)\) then?

Best ResponseYou've already chosen the best response.1Yes. So it's F(x)=15x42...But what method is it??

Best ResponseYou've already chosen the best response.1@ParthKohli ?? is that right and is it equal to F(x) or y?

Best ResponseYou've already chosen the best response.1Yes, substitution maybe. I haven't heard of different methods: this one is the only one I know of.
