Best ResponseYou've already chosen the best response.0usual idea is to imagine there are are two ways and then show they are the same. so maybe put \[f(x)=e(x)+o(x)=\frac{f(x)+f(x)}{2}+\frac{f(x)f(x)}{2}\] where \(o(x)\) is odd and \(e(x)\) is even and then show that \(e(x)=\frac{f(x)+f(x)}{2}\) and \(o(x)=\frac{f(x)f(x)}{2}\)
