Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=−x2f(x) = -x^2\newlineg(x)=3x+3g(x) = 3x + 3\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. Given Functions: We have: \newlinef(x)=−x2f(x) = -x^2 \newlineg(x)=3x+3g(x) = 3x + 3 \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+(3x+3)(f + g)(x) = -x^2 + (3x + 3)
  3. Combine and Simplify: Combine the terms to simplify the expression.\newlineSince there are no like terms to combine with −x2-x^2, the expression is already in its simplest form.\newline(f+g)(x)=−x2+3x+3(f + g)(x) = -x^2 + 3x + 3
