Best ResponseYou've already chosen the best response.1f(x) is a function containing x if you want f(3) you want a function containing 3's so wherever x was originally you would replace them all with 3

Best ResponseYou've already chosen the best response.1so for your function f(x) = x2 − 13 you want to replace all x with 3 so you get f(3)=3²13 then do the same with g then add your answers
