Best ResponseYou've already chosen the best response.0work from the inside out \[g(f(x))=g(4x^2+x+1)\] then since \[g(\spadesuit)=\spadesuit^22\] you have \[g(f(x))=g(4x^2+x+1)=(4x^2+x+1)^22\]

Best ResponseYou've already chosen the best response.2well, we know that g(x) = x^2  2, right? if we replace x with f(x) on both sides, what do we get?
