Q. What is (f+g)(x)(f + g)(x)?\newlinef(x)=4x+2f(x) = 4x + 2\newlineg(x)=x2g(x) = x^2\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). The correct formula is (f+g)(x)=f(x)+g(x)(f + g)(x) = f(x) + g(x).
  2. Substitute Values: We have f(x)=4x+2f(x) = 4x + 2 and g(x)=x2g(x) = x^2. Substitute these values into the formula to get (f+g)(x)=(4x+2)+x2(f + g)(x) = (4x + 2) + x^2.
  3. Simplify Equation: Simplify the equation (f+g)(x)=(4x+2)+x2(f + g)(x) = (4x + 2) + x^2 to find (f+g)(x)(f + g)(x). Since addition is commutative, we can rearrange the terms to write the polynomial in standard form, starting with the highest power of xx. (f+g)(x)=x2+4x+2(f + g)(x) = x^2 + 4x + 2
