Best ResponseYou've already chosen the best response.1are you able to evaluate f(x) when x = 3 ?

Best ResponseYou've already chosen the best response.1how about the value of g(3) ?

Best ResponseYou've already chosen the best response.1now just add the values of f(3) and g(3)

Best ResponseYou've already chosen the best response.1this works because (f+g)(x) = f(x) + g(x) (f+g)(3) = f(3) + g(3)

Best ResponseYou've already chosen the best response.1(f+g)(3) = f(3) + g(3) (f+g)(3) = 21 + (4)

Best ResponseYou've already chosen the best response.1the notation `(f+g)(3)` does NOT mean `(f+g) times 3`

Best ResponseYou've already chosen the best response.1f(3) does not mean f times 3 it means "replace every x with 3, then evaluate"
