Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=−x2+8xf(x) = -x^2 + 8x\newlineg(x)=−3xg(x) = -3x\newlineWrite your answer as a polynomial or a rational function in simplest form.\newline______
  1. Given Functions: We have:\newlinef(x)=−x2+8xf(x) = -x^2 + 8x\newlineg(x)=−3xg(x) = -3x\newlineNow, let's add these two functions to find (f+g)(x)(f + g)(x).\newline(f+g)(x)=f(x)+g(x)(f + g)(x) = f(x) + g(x)\newline(f+g)(x)=(−x2+8x)+(−3x)(f + g)(x) = (-x^2 + 8x) + (-3x)
  2. Addition of Functions: Combine like terms to simplify the expression.\newline(f+g)(x)=−x2+8x−3x(f + g)(x) = -x^2 + 8x - 3x\newline(f+g)(x)=−x2+(8x−3x)(f + g)(x) = -x^2 + (8x - 3x)\newline(f+g)(x)=−x2+5x(f + g)(x) = -x^2 + 5x
