Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=−x2f(x) = -x^2\newlineg(x)=−x2−10xg(x) = -x^2 - 10x\newlineWrite your answer as a polynomial or a rational function in simplest form.\newline______
  1. Identify formula: Identify the formula for (f+g)(x)(f + g)(x).(f+g)(x)(f + g)(x) is the sum of f(x)f(x) and g(x)g(x).(f+g)(x)=f(x)+g(x)(f + g)(x) = f(x) + g(x)
  2. Add functions: We have:\newlinef(x)=−x2f(x) = -x^2\newlineg(x)=−x2−10xg(x) = -x^2 - 10x\newlineNow, we need to 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)+(−x2−10x)(f + g)(x) = (-x^2) + (-x^2 - 10x)
  3. Combine like terms: Combine like terms.\newline(f+g)(x)=−x2−x2−10x(f + g)(x) = -x^2 - x^2 - 10x\newline(f+g)(x)=−2x2−10x(f + g)(x) = -2x^2 - 10x\newlineThis is the simplified form of the sum of the two functions.
