Best ResponseYou've already chosen the best response.0f(x) = \[\sqrt{x+2}\] ; g(x) = \[\sqrt{3x}\] find (f+g)(x) how would I do that?

Best ResponseYou've already chosen the best response.0(f+g)(x)=f(x)+g(x) \[(f+g)(x)=\sqrt{x+2}+\sqrt{3x}\] this is the answer you cant do anything

Best ResponseYou've already chosen the best response.0since inside of the roots are different you cannot make addition

Best ResponseYou've already chosen the best response.0if it was (f*g)(x), you can multiply the expression inside the radical signs since they have common indices.

Best ResponseYou've already chosen the best response.0(f*g)(x)=f(x)*g(x) \[(f*g)(x)=(\sqrt{x+2})(\sqrt{3x})\] \[\sqrt{(x+2)(3x)}\]\[\sqrt{x^2+x6}\]
