Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=−3x2f(x) = -3x^2\newlineg(x)=5x+4g(x) = 5x + 4\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)=−3x2f(x) = -3x^2 \newlineg(x)=5x+4g(x) = 5x + 4 \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)=−3x2+(5x+4)(f + g)(x) = -3x^2 + (5x + 4)
  3. Simplify expression: Simplify the expression by combining like terms.\newlineSince there are no like terms to combine in this case, the expression is already in its simplest form.\newline(f+g)(x)=−3x2+5x+4(f + g)(x) = -3x^2 + 5x + 4
