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