Q. What is (f−g)(x)(f - g)(x)?\newlinef(x)=−x2f(x) = -x^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 difference 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. Substitute functions: We have:\newlinef(x)=−x2f(x) = -x^2\newlineg(x)=−2x+4g(x) = -2x + 4\newlineSubstitute these functions into the formula for (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)−(−2x+4)(f - g)(x) = (-x^2) - (-2x + 4)
  3. Simplify expression: Simplify the expression by distributing the negative sign and combining like terms.\newline(f−g)(x)=−x2+2x−4(f - g)(x) = -x^2 + 2x - 4
