Documenting Profit Modeling Procedures

You are working as an operations analyst assistant at a retail logistics firm. Your company models its monthly warehouse revenue with the function f(x)=3x25x+7f(x) = 3x^2 - 5x + 7 and its monthly utility expenses with g(x)=x24x3g(x) = x^2 - 4x - 3, where xx represents the volume of processed inventory. Your supervisor has asked you to document the standard procedure for finding the net performance difference, defined by the function (fg)(x)(f-g)(x).

From memory, write a short guide explaining how to perform this subtraction. In your response, make sure to:

  1. State the fundamental algebraic formula that defines the difference function (fg)(x)(f-g)(x) in terms of f(x)f(x) and g(x)g(x).
  2. Describe the crucial rule regarding signs that must be applied when distributing the subtraction sign across the terms of g(x)=x24x3g(x) = x^2 - 4x - 3.
  3. Outline the step-by-step process of grouping and combining the like terms to arrive at the final simplified polynomial.
  4. State the final simplified polynomial expression for (fg)(x)(f-g)(x).
